I'm using FFMPEG to convert VOB files to MPEG2 using ffmpeg -i file.vob -c copy
out.mpg.
It's converting the video fine, but the audio doesn't play on the resulting files. I get the
[mpeg @ 0x118afc0] max_analyze_duration 5000000 reached at 5005000
error, but setting -analyzeduration to 9999999 or higher doesn't get
rid of the error.
I think it's reading the stream correctly:
Metadata:
encoder : Lavf53.32.100
Stream #0:0: Video: mpeg2video, yuv420p, 720x480 [SAR 8:9 DAR 4:3], q=2-31,
6124 kb/s, 29.97 fps, 90k tbn, 29.97 tbc
Stream #0:1: Audio: ac3, 48000 Hz, stereo, 256 kb/s`
Here's info on my install

You are trying to mux an AC3 stream into an MPEG container. You cannot do this. You could use a different container
ffmpeg -i file.vob -c copy out.mkv
or perhaps allow FFmpeg to transcode the audio
ffmpeg -i file.vob -c:v copy out.mpg
