There's also a risk of mencoder screwing up and dropping or
duplicating some frames when doing the -ovc copy, which is horribly
broken with -ovc copy.. I would recommend the method of doing audio as
the last pass instead of the first. Then, the only time you have to
use -ovc copy is on your mencoder-generated source, which is less
likely to be messed up than random mpeg sources with all kinds of
bogus frame structure..
