This is in.

By the way, can anyone point me to some specs for MPEG2 formats.  The 
selection of the audio track to use was based on a sampling of some DVD 
rips I had, however it's not right for ALL DVD rips.  I assume theres a 
rule to follow for always getting the main audio track for a given 
stream, I just don't know what it is.
