I tried in Ubuntu 10.10 and 11.04 but cannot reproduce your problem. Which FFmpeg packages are you using? Can you paste the output of:

ffmpeg -i rendered_file.vob

With one of the file rendered without audio?

I have been using ffmpeg from git for quite some time without any problems. After using ffmpeg -i xx.vob I noticed there were mismatch? problems so I re-build again yesterday. That problem has now gone away.

as requested (and more,sorry):-

Selected zone. Rendering 2 pass

I removed the audio and it rendered fine. I converted the .mp3 to .wav and it rendered fine, three times!

I have had problems with .mp3 in the past and promised myself to convert then to .wav every time, but... I wont forget again.

Thanks for your time.

The crashes are probably caused by the "insufficient thread locking around avcodec_open/close()". That was recently fixed in the latest development version of MLT.

I'm not sure about the missing audio. I haven't seen that myself.
