Philips SPD2514T DVD Writer Review

Philips SPD2514T DVD Writer A DVD Writer has become an important hardware for a PC. A well known brand Philips, offer a writer that can do a maximum writing up to 20x on DVD-/+R.
The Philips SPD2514T that we review is already use firmware ver. P1.1 (the latest version). To eaze the firmware update, we can use the Philips Inteligent Agent. This software will automaticaly detect the installed firmware and give us a recomendation if there is an update. Unfortunately, this software is not bundled along with the product, so we have to download it from the Philips Official Website.

Alright, here's the test.

When we use a 52x max writing CD-R, the Philips SPD2514T only shows its maximum writing ability, which is 48x. But a great operation time was shown when we tried to write a DVD-R. And more outstanding result occur when we used an over-spec-able disc up to 20x, despite the disc itself only had 16x maximum writing. In that case, the 20x maximum writing that the product claim is true and worked very well.

On DVD-R DL, the writing speed was limited to 4x writing speed option, that because the disc speed is limited on 4x. The test was resulting an optimum performance. The result was also great when we used it as a reading media. The average maximum reading time was exceeded on all media.

What Philips SPD2514T offer is really interesting both on spesification and performance. The high speed writing ability become an important value and noteworthy, because according to our test it gave a maximum performance. Not to mention the competitive price.

Whats is CSS?

CSS has been developed for the first time in 1997 as a way for Web developers to define the appearance of their Web pages. It is intended to allow developers to separate content of the HTML design so that can carry over the function it was originally founded on - the markup content, regardless of the design and layout.
CSS has not gained popularity in the mid 2000, when Web browsers began using more of the basic police and color aspects of the SSC. And now, all modern browsers support all CSS level 1, most CSS level 2, and some aspects of CSS level 3.
The Web designers who do not use CSS for the design and development of Web sites are becoming a thing of the past. And it is undoubtedly also important to understand that CSS is to know HTML - and some would say it was more important to know CSS.
CSS is an abbreviation, It means Cascading Style Sheet.
Stylesheet refers to the document itself. The style sheets were used to design documents for years. They are the technical specifications for a layout, whether print or online. Print designers use style sheets to ensure that their designs are printed exactly to specifications. A stylesheet for a webpage serves the same goal, but with additional features also display engine (the browser) explains how to make the document being viewed.
Cascade is the special part. A stylesheet Web is intended to cascade through a series of style, like a river over a waterfall. The water in the river all the hits rocks in the waterfall, but only those at the bottom affect exactly where the water will flow. The same is true of the cascade in Web style sheets.
Each Web page is affected by at least one stylesheet, even if the Web designer does not apply to all styles. This stylesheet is the agent user stylesheet - style default Web browser uses to display a page if no further instructions are provided. But if the designer provides further instructions, the navigator must know what instructions have priority.
For example, in my Web browser, the default font is Times New Roman size 16. But nearly no pages I visit in the display are the family and size. The reason is that the second cascade defines style sheets set by the designers to redefine the font size and family take precedence over my default Web browser.
Where is CSS used?
CSS is used to the style of Web pages. But it is more than that. CSS is used to the style XHTML and XML. This means that anywhere you have tagged in XML (including XHTML), you can use CSS to define how it will be.
CSS is also used to define how Web pages should look seen in other media as a Web browser. For example, you can create an impression stylesheet that define how the Web page must be printed and another stylesheet to view the Web page on a projector for a slide show.
CSS Why is it important?
CSS is one of the most powerful tools a Web designer can know it because you can affect the whole mood and tone of a website. While writing style sheets can be updated quickly sites and help change what is in order of priority or value without changing the underlying XHTML. T
he challenge of CSS is that there is so much to learn. But it does not seem like her. After all, there are only about 60 properties in CSS level 1 and around 70 in CSS level 2. In comparison with the number of HTML tags and attributes to learn, which can feel like a cake walk.
But because CSS may cascade, and combine and browsers interpret the guidelines differently, CSS is more difficult than HTML. But once you start using it, you will see that harnessing the power of CSS will give you more options and allow you to do more things with your Web sites.
If you want to be a professional Web designer, you must learn Cascading Style Sheets. But fortunately, they are fun to learn.

What Is JavaScript?

JavaScript is a scripting language most commonly used for client-side Web development. It was the original dialect of the ECMAScript standard. It is a dynamic, weakly typed, prototype based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but easier for non-programmers to work

Although best known for its use in Web pages (as a client-side JavaScript), JavaScript is also used to the Scripting access to objects embedded in other applications.

JavaScript, despite the name, is basically nothing to do with the Java programming language, although both have the common C syntax, JavaScript and Java copies of many names and naming convention. The language was originally called "Live script", but was renamed in a co-marketing deal between Netscape and Sun in exchange for Netscape bundling Sun's Java runtime environment with its then dominant browser. The main design principles within JavaScript are a legacy of the Self programming language.

"JavaScript" is a trademark of Sun Microsystems. It was used under license for the technology invented and implemented by Netscape Communications and current units such as the Mozilla Foundation.

Troubleshoot Your Soundcard

Computers use sound cards to send sound signals from your computer to your speakers. A sound card is a piece of equipment in the computer that can be integrated into the motherboard or a card. These cards are usually PCI which is the most common add-on card type. , There are companies that are external USB sound cards, but they are not very common.

These sound cards drivers use to communicate with the operating system. For most users of the operating system is a version of Microsoft Windows. Of course, there are other operating systems such as Mac OSX and Linux. If the operating system does not have the driver is installed or not at all a driver, he will not know what to do with new equipment and most of the time a return error.

There are a few ways to install the drivers for your sound card. The most common way is to install the driver software from the CD that came with the sound card. Sometimes you install the software before the card and sometimes you install the card before the software according to the manufactures instructions. The software drivers and any other sound management of public services such as a mixer for example. Windows also a way for you to manage your sound settings.

If you do not have the CD that came with your sound card you can usually download the manufactures website if you know the model of the sound card. Another way to install the drivers is updating Windows. This will only work if Windows recognizes the card and knows what drivers to be searched. Sometimes, if you restart your Windows computer that you have new hardware and ask you how you want to install this software. There will be a section to ask you if you allow Windows to go online searching for drivers and see if it can download the correct driver.

You can also go to Device Manager and find the sound card and double click it to open its properties. Then go to the Driver tab and click update the pilot and follow the instructions to search your computer, CD-ROM or Windows Update. If you do not see your sound card to watch an unknown aircraft or an icon with a yellow question mark or exclamation point on this. This means that Windows sees the device, but there is a problem with the driver. This is a good place to look if you have any problems with the sound a sound card that accompanies your computer. The driver could have become corrupted or May you have inadvertently downloaded a new driver during Windows Update, which is originally a conflict. There is a button to push back the driver to return to the previous May solve your problem. You can also remove the device Device Manager, restart the computer and let Windows detect the sound card again and reinstall the drivers.

If you have problems with a sound card does not work all of the sudden and it looks fine in Device Manager and then the next step is to check your speakers and a loudspeaker connection. If you have any other speakers or even an iPod or portable headset you can connect them and see if you get the sound. In this case, your speakers are most likely not much more. Also make sure they are plugged in the correct form and that is in any way.

Next make sure the volume is mounted. Some speakers have separate volume controls on the speakers themselves can be used in addition to the volume control in Windows. The speaker is usually in the lower right corner by the clock and you can click on it to adjust the level. You can also double-click on it to make further checks of the noise level.
Master Volume ControlIf you do not have the speaker icon on the clock, you can add it by going to the Control Panel and click on the Sounds and Audio Devices icon. From there, check the box that says Place volume icon in the taskbar.
The next step is to check several options under control panel and the Sounds and Audio Devices. Under the Volume tab, you can check the volume, make sure it is not on mute, and verify the speaker volume and configuration. The Sounds tab lets you configure the sounds play in which events in Windows. You can also turn off the sounds of Windows if you do not like them. It will not affect your other sound settings. The Audio tab lists your sound device for reading, recording and MIDI music. Make sure the default device is what you have installed on your computer and not another appliance or device that older May were removed. The Voice tab is similar to the Audio tab exception of his voice for playback and recording using a microphone. The tab lists equipment installed your audio CD / DVD. You can do basic troubleshooting here and the term of his assistant solving problems by putting the camera and clicking on the button Troubleshoot. You can check the properties of the device and the driver configuration Properties button.
Sound and Audio devices propertiesAnother trick is to make the right sound card housing and save another location if you have one. If your sound card is built into the motherboard this is not an option but you can add a sound card size and use that instead of building on the sound card. May You want to go into the BIOS to disable the sound card board in order to avoid any conflict. Finally, it is possible that the sound card loudspeaker or taken on the card was bad and you have until the end of May to replace it with a new one.

Nvidia Had Problem With Laptop Chips

Nvidia discovered a problem with some graphics chips shipped in large quantities "of laptops, the company said Wednesday.

Nvidia has not determined the exact cause of the problem but said it relates to a packaging material used with some of its chips, and the thermal design of some laptops. The processors generate considerable quantities of heat.

To tackle the problem, the company publishes a software driver that causes fans of the operating system to start earlier and reduce the "heat stress" on the chips. The driver was provided to laptop makers directly, "said Derek Perez, a spokesman for Nvidia.

Nvidia will take a charge against the second quarter of U.S. $ 150 million to $ 200 million to cover the cost of repair and replacement products, which include graphics processing units and media and communications processors. He did not say specifically which of its products were affected.

The products were lacking on the ground to "higher than normal rates," said Nvidia. In a filing with the U.S. Securities and Exchange Commission, she spoke to its supply chain to obtain reimbursement for a portion of the costs.

The company also had other bad news Wednesday. He said it was lowering its revenue forecast for the second quarter due to price pressure and delayed product ramps. The company now expects revenue to be between $ 875 million and 950 million dollars.

Repair DVD, DVD and scratched Unfinalized DVD collection of tips and tricks.

Repair DVD, DVD and scratched Unfinalized DVD collection of tips and tricks.

by: Lance Carr

Simple and (I hope!) Free treat procedures finalized, unsuccessfully, DVD, DVD damaged or DVDs that have not been properly burned by a video camera recorder or burner and some corrupt data .

It is a good idea for you to first consider other possible causes of what appears to be a DVD errors, as a hard surface dirty, a dirty lens in the DVD player or other software and equipment related problems. Before embarking on one of the following cases, you must eliminate all possible causes have problems with a DVD. Make sure your DVD burner has the latest firmware going on the website of manufacturers. Check if the media (make and model) is compatible with your CD / DVD player. Once you are sure you have finalized, without success, a DVD or a DVD of corruption, you can start.

Scratch DVD

A simple visual inspection of the surface of the disc will tell you immediately if your first problem is physical damage on the disc. If you can see a scratch or scratches on the surface this May must be addressed first. I say "May" because I personally use DVDFab to check to see if the hard copy before I embark on another course of action. DVDFab can read in a large number of errors surface because of its superior algorithms so I always take the lazy road and see if I can just make a new copy. Now, if you can go online and buy expensive DVD scratch repair kit. Or you could do like me and go to your local hardware store or even your own garage! All you will need is a bottle of any neutral color (bright) products polishing car. Turtlewax happens to be the one I use. Take a very soft cloth (not paper towel), apply a little polish the surface of the disc and gently (remember, this is not a car!) Scrub hard. Use blows right of the disk center and the outer edge and continue to do so until you can see zero or disappear or reduce significantly. Then using the same movement and new tissue buff the disk to its original shine. Now, try DVDFab. If you are still unsuccessful repeat the process until you can be sure, again by visual inspection that the problem now is not coming from a damaged disk surface.

DVD data repair or recovery

The software you can use for this are DVDFab, Nero 8 (trial) and Isobuster. In the case of Isobuster you can try characteristics without beginning, but failing that the full version must be purchased. A search on Yahoo or Google, you will find the sites.

Put the problem disc into the DVD player to your computer later:

1. DVDFab. Try using DVDFab first, as he did the best algorithms for reading anything on a DVD, including how it fits with the DVD player, honestly sometimes I think that it would be a bagel if you put it in there!

Select "DVD to DVD." DVDFab will now try to read the contents of the disk and, if she can write the contents of a folder on your hard drive. It's as simple as that. It is either going to work or not! If they do so then the copy you have on your hard disk will be fully repaired and you can burn a new copy.


2. Isobuster. Using the free functions try to make a disk image file and burn another DVD. Isobuster has three other ways of dealing with data corruption. It can replace the corrupt with nothing, with false data or with a series of zeros. It will give you the choice and select them simply in order to try until each one. Isobuster not create the disk image file if it knows that it will succeed. If Isobuster created the file (note where it was going to put the first!) You re-name the extension. Iso. Use the disk image file to burn a new DVD disc. At this point, if you now have a new disc, you should check that the new carefully. There is always the possibility that Isobuster just made a perfect copy of your bad! So, you now have a brand new bad!

Failing: You will have to pay for the full version of Isobuster ONLY buy it if you got this far. If Isobuster free could not even read the disc as not to disturb. > From this point forward the best you can hope is the extraction of MPEG video files or data files on the disk. You will lose menus and video May you lose a part of the video or data.

A. Beginning Isobuster then load the disc.

B. When Isobuster detected files on the disk run the program find files and folders "under the" File "menu.

C. You will now have an entrance on the left column of "files and files found by their signature."

D. Select, then "File", "files found through their signature" then "Extract the files found through their signature." Choose a location and let it run.

Now you have all the files where you chose to go. Those with the extension. VOB are MPEG files from your hard wrapped in the VOB container. They can then be imported into a video editing program using the "Import DVD / VR" or function can be read by most software DVD burning.

Unfinalized discs.

If possible try to get the device used to create the disc to be finalized. If this is not possible or device fails to complete successfully the disk you use the May Isobuster routine above.

If you were left with another disc perfectly well, but unfinalized, proceed as follows. This requires Nero 8 (trial version). Go to the site of Nero, download and install Nero 8.

Yes, it is high ... sorry!

Place the disc into the computer unfinalized DVD tray. Open Nero StartSmart 8. Click on "create and modify" at the top of the screen. Click on "author, edit and capture video." NeroVision 5 start. Click on the disk tools menu and click on "finalize the disc." In the option box that appears choose "no menus" and let it run. We hope you have now finalised a disc which is readable.

Hope this helps!
