If your source is NTSC, make sure you do a proper inverse telecine to
fix this problem.

If it's not the case, you may try larger values of -mc 0, and see what
happends. You may also try to copy another track (maybe for some
reason the type of audio track that you use is not well supported).

If it still doesn't work, you may try to disable sound altogether with
"-nosound", but it may lead to huge desync when trying to mux audio
and video back.

Not that I know of :-(
