Windvd 8 crashes on play from folder

[cgguy]

I've installed the trial version but it hard crashes my computer when I play movies from a folder. I can play DVD's from the drive or I can play individual VOB files from the hard disk.

The movies play fine with WinDVD 5 and other freeware dvd players.

It seems to be an interrupt issue -- non-handled interrupts go way up before it crashes.

Does anyone know of a troubleshooting guide? I have the latest video drivers and XP SP2 installed.
