yea, I'm beginning to think that this widespread.  Either way, I think
I'm trying to maybe start using h.264, but the one video I created
doesn't playback any sound in myth (but does in quicktime on another
machine).  Either way, I'm sure this is simply related to the fact
that I don't have mp4 completely configured right for myth somehow?

Wish xvid would work though.
