I found another way to multiplex mpeg2 with an application for Mac OS X
called "MPEG Streamclip". I use the application a lot, but I didn't realize
it could mux. If you have an m2v file and and the right audio file such as
ac3 in the same directory and with the same names except for the name
extension, you can feed the m2v file to MPEG Streamclip, and it will mux on
the fly for playback. Then you can save the results as an mpg (or rather
more precisely, as an "mpeg") file.
