Exception: Audio is not found [AutoGK]

[corn]

I'm trying to convert a special features dvd into .avi format but for some reason the VTS_01_0.IFO keeps giving me this weird exception about audio not found. All the other .IFO files off the dvd worked except this one.

Whenever i try to convert, it starts up the virtualdub mod and then stops. Any help would be greatly appreciated.

also while the log says my OS is vista, but its acutally windows 7 RC1.

Did you decrypt each episode to the hard drive separately, as you should have? If so, what happens when you load the VOB(s) for the episode, rather than the IFO? If you already have the whole DVD on the hard drive, use PGCDemux to extract a PGC VOB of that episode and load that.

The PGVDemux worked perfectly thanks so much!
