I create uncompressed avi files from Virtual Dub including avi audio (full processing mode). Under normal circumstances I get great results using the stadard VCD PAL template in tmpgenc. Typically my clips are from hi-8 movies and are approx. 2-3 minutes in length, however if I creep up to the 5 min mark I hit a problem with the audio in my converted mpeg file. The audio is only there for the first minute or so of the playback and then just stops, the vid however will carry on playing to the end of the file. I guess I am hitting some kind of threshold here - can it be cured?
