I have an .avi file with 2 audio streams that I'm trying to re-encode with AutoGK (the aspect ratio is off). When I start the job though, AutoGK gives the "Unsupported audio type" message and stops.

The 2 audio streams are list in the Audio track window as:
192 Kbps AC3 1ch
130 Kbps MPEG-1/2L3 -- this is the problem one it's stalling on

Media info on the 2 audio streams:

I have both of those codecs installed and use them often, and even updated them today, but I'm still getting "Unsupported audio type".

What am I missing or doing wrong? I don't see anything out of the ordinary in the 2nd audio stream. I can process the audio stream with either GoldWave and Audacity, so I definitely have the proper codecs installed.

Yes, it's mostly AR being off that bugs me. The commentary audio track is out of sync a bit also, but since it cuts to very little movie dialogue between the comments, I wasn't going to worry about that.

Thanks, I'll give that a try since I still can't seem to find a way to stop AutoGK from choking on that one audio stream.
