I installed some Pinnacle video editing software the other day, and somehow it messed up my CD-ROM registry entries. Caused my ROM drives not to be recognized by Windows XP. So I followed the directions off Pinnacles site and all was good. Today I realized I can't use WinXPs built in CD-ROM burning (drag and drop from explorer) features. I checked the device manager and it lists my CD-ROMs and "unknown". I tried uninstalled, reinstalling, etc. Perhaps I deleted a registry key I shouldn't have? Is there a way to fix this, or have windows rewrite the rom entries? Thanks.
