I am multiplexing a m2v file that I created from an avi with TMPG with a 2 channel ac3 stream that I converted from wav using besweet and after I finished multiplexing the files together in TMPG it came back with a message that read:

11 s packets cause buffer underflow.
Mpeg may be unreadable.


Any I deas what this is? Or what it is caused by?
