There may be something up with the laser on your DVD drive, which would suggest a hardware fault perhaps.  Im not too sure about software stuff but there may be settings that are causing it to stop prematurely. Check that all your DVDs are clean and that the bay itself is fee from dust etc...

Before buying a new one, try this:  First, check the cables (power and ribbon) to make sure they're seated properly.  Next, using the Device Manager, RIGHT click on the drive that's shown, and choose "uninstall".  Say "Yes" to the next question.  Then re-boot, and if the drive is working, Windows will find it as "new hardware" and install the drivers for it.  If it is still not recognized or not working, then sure, go ahead and purchase a new one.  By the way, you might as well get yourself a DVD drive if you're getting a new one, since it'll handle both DVD's and CD's as well.  Good luck.

Idiot Check,\n Does the DVD work in a different player - If so then the disk is not the problem.\n Try a different DVD - If the second disk works but the first disk does not then your disk may be "finger printed" -wipe it off.\n\nNone of those work then you do have either a hardware decoder or a software decoder?\n\nIf it is a software decoder then posably the drivers are messed up

A couple things:\nIs the software you're using updated? Check the help files to see how to update your software.\n\nAre you playing a DVD or just a video clip file? You might want to check if the DVD is dirty or if the video clip was badly made. You might want to check your DVD rom drive if its dusty or so.

Try with a normal Data CD first(not a CDR). A pressed CD is much more accurate than a CDR and will be easier for the drive to read (most of the time). If it does read then you may wish to try and clean the dive using a CD/DVD cleaner. You may be lucky. if it doesn't read you may want to check those cables again and then use the cleaner but you are unlikely to have much luck if it's not  a silly thing with the cables. Dont bother trying to get it fixed or generally fiddling about just get another from any one of the millions of Retail outlets such as Dabs and Aria ..etctec\n\nIve been repairing comps for 20 years and CD drives are too awkward and too cheap to fiddle with ...John

That depends on how it was burned. There are region-free burners. Also, you can generally read most regions of DVD's in a computer DVD drive, but if you have a DVD player, than it's a different story. You should find out what region the DVD was burned for (if any), and then check that against the regions readable by the hardware that you are using to read the DVD.

Clean the drive using a cleaning CD. In most the cases such problems are caused by moisture or dust on the readind lens. Make sure that you run the cleaning CD multiple times. \n\nAs you said that other HDD video files perfectly there is nothing wring with the software which runs it or the codec associated with it. \n\nAlso make sure that it is not a problem with the DVD Disc.

It doesn't sound like something that can be repaired without removing the DVD assembly.\n\nI assume you've tried other DVDs in it to elliminate the possibility of a bad DVD?

Try restarting your computer. If the drive is removable, try taking it out and putting it in. Try going to device manager and making sure there are drivers installed for it. You can do this by going to start, right click on my computer, click properties, click hardware tab, then click the device manager button. Look for anything with an ! or ? icon. If there is one on the CD/DVD drive then it's a driver problem, easily fixed. I'd tell you where to get the driver if I knew the model of your computer.\n\nAnd if none of these work, it may be the drive fried or got disconnected from the board.

That usually is a good sign that your installation disc is damaged/corrupted.  You may want to obtain a fresh copy.

many CD-ROM drives have DVD capability.  But you may need to download and install extra drivers for DVD functionality.

Firstly, make sure your CD-ROM drive is compatible with DVD media. You should be able to see the DVD logo on the front of the drive or you can find your drive's properties in Device Manager. \nSecondly, you need a DVD decoder and a program like Windows Media Player to view DVD's on your system. \nTry visiting http://download.com/ and searching for DVD decoders.

When you install the software, do you reboot the computer? How many drives do you have? Check your program to see if you are loading the disc in the one it is expecting to see the blank disc in.\n\nI had a drive go bad and it didn't see anything. You can check that out by putting a program cd in and seeing if it opens or by going to my computer and looking.\n\nAlso, check out your hardware profiles. Look to see if it(the cd burner or reader) is being recognized and the drivers are working properly.
