I'm having trouble converting vobs and mpegs to divx/xvid with AutoGK.

Occasionally (probably once in ten) it will encode the video correctly and give me a full divx/xvid avi file, but all the other times it stops part of the way through saying that it's can't process the filename\agk\frame.log file because it's being used by another process.

I've tried everything I can think of; restartnig, making sure no other programs are running, etc, but it still nearly always fails to finish the encoding. Does anyone have an idea why? My CPU is a Core 2 and I've got 1gb of ram, plenty of hard disk space. I can't think of anything to correct it and its really getting on my nerves! I just want to be able to set it to convert and leave it to it without all this fannying around!

Thanks guys
