I have DVDFab 126.96.36.199 Platinum with Options (purchased through DVDfab.com). Setup file is DVDFab5232_avangate-689.exe.
I saved the IFO files to the desktop to see if they were able to be accessed.
I was able to access the drive through explorer.
Ada at DVDfab said to uninstall the Roxio software and remove XP SP3. I did this but still no go.
Just reinstalled XP and installing Sonic Cineplayer DVD Decoder Pack after I set up my internet connection. Once this is done I'll install DVDfab again and follow the instructions provided by StormJumper.
