1. Open XP's "Help and Support Center"
2. Type: DVD in the search box, hit enter.
3. Click on "DVD Troubleshooter".
4. You probably need to purchase a new DVD decoder.
I also installed Microsoft XP and erased Me. Now I can not play dvds so I
downloaded PowerDVD from Cyberlink and it is not showing up in Accesories
were it was supposed to be put. I can find it in add/remove programs but I
can not figure out how to use it? I have tried to reinstall it with no
change.???????????
If you just purchased the decoding software, then you will play your DVDs in
Windows Media Player. If you downloaded and installed the full version of
PowerDVD, there should be an icon on the desktop.
