Addition to my post above:
The registry also needs modified for User access to DVD drive in
DVDFab:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWSNT\CURRENTVERSION\WINLOGON
allocateCDRoms = 1
This works on W2k & WinXP Pro (I'm not sure of any others).
I forgot about this step until I setup my XP machine.
Both machines use a SATA DVD drive so I don't know if it will work on a IDE drive.
I wonder if this has something to do with the User access rights to SPTI. This is the same fix I needed for another backup program.
