    Hello and welcome to Techspot.

    Please would you take a few moments to read this post. A message for all newcomers. Thanks.

    In answer to your problem. Your dvd rom`s laser is dying. Hence the gradual decrease in your dvd rom`s performance.

    You need to replace your dvd rom. They`re only cheap, and this will undoubtedly solve your problem.

    If your drive reads cd's, but not dvd's That indicates that the hardware works fine. You will need to edit the registry inorder to fix this problem.

    1) click the start menu
    2) click on "run"
    3) type "regedit" and click ok
    4) go to string key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
    5) delete "upper filters" and "lower filters in the right side window.
    6) right click my computer in the start menu.
    7) click properties
    8) go to the hardware tab
    9) click device manager
    10) expand the dvd/cdrom drives
    11) right click the dvd rom and click uninstall
    12) restart computer

    after restarting, windows should automatically install a clean ROM drive and it should read DVDs just fine if you have the correct DVD decoders.

    I`m having the same problem.. What would cause the registry to change and what are those filters for??? Mine was working perfectly then about an hour later it wouldn`t work. Except for the cd part.. Just curious, mine is still under warranty and less then a year old..
