If the stuff is out of sync then the whole process is broken - e.g. the
audio is much longer than the video. This already happens at the
mencoder stage, not when putting both into Matroska. Using three-pass
encoding with mencoder is known to be buggy, especially if you're
dealing with telecined content. Please search the mplayer-users mailing
lists for better ways to do this.

unconstitutional too, since clearly it de-emphasizes the commercial
nature of normal human interaction, and probably is a major impediment
to the commercial growth of prostitution. - Linus Torvalds
