ok... first, the drive is the original factory drive and there were no installation discs. All the install/restoration files are on a separate partition on the hard drive which I can only access through a system restore program outside of WinXP.
yrag...I don't have an nVidia motherboard. This is an hp Pavilion with a P4B-LA board. I can't find anything under IDE controllers referring to the DVD drive in device manager. Under IDE controllers I have entries for Intel Bus Master IDE Controller, Primary IDE Channel, and Secondary IDE Channel.
I have a separate entry for the DVD-ROM in Device Manager. I can't find anything there that would indicate whether the device is "Multi-Word DMA-2 compliant or better. All I see is a driver listing which tells me that it is a Micrsoft Driver, dated 7/1/2001, version 5.1.2535.0, and that it is signed.
The drive does read data from everything except DVD's. Even if I try to check it with explorer, it won't show a disc in the drive if the disc is a DVD. If I put any kind of CD in the drive, everything works properly.
Lastly, clicking on DVDplay.exe has the same result, a message asking me to a disc in the drive. (Yes, there was a good DVD in the drive at the time.)
And thanks again guys for the help. Sorry I took so long getting back to you... the girlfriend and kids had a surprise party for me.
