I normally convert .avi files with mainconcept mpeg encoder to DVD mpeg2 files then use TMPGenc dvd author or dvdsanta

Think your problem could be with the compression that’s used in .avi files for the audio, there is a program that will uncompress it but cannot recall the name of it,

Max

Nero will do with the vision express add on. As long as it is a valid avi file. What can make it invalid is the way it is encoded, normally the problem is the audio encoding is at the wrong setting, a lot are done at (if I remember correctly) at 44.1khz when it should be 48. You can reencode with tmpgenc.

Also has the file been encoded at NTSC rather than PAL or vice/versa this can also cause problems.
