I ran demux to .m2v and .mp2 and then tcrequant on the .m2v file(if i need to 
shrink the size) and then mplex. 

Then check the size of the created audio file. If its around 50MB for a
44 min program its truncated and the DVD will only have audio for about
the first 15-20 mins.

This doesn't happen all the time and it just maybe something i am doing
wrong. I have'nt played with it a lot.
