Best option, get a hardware encoder card so you start out with something 
more generic.

Second best option, rewrite the encoder routines in MythTV to use a more 
sensible format.  This has actually been done at least once, but it 
never got cleaned up and committed.

What you're probably looking for, use mythtranscode's fifo options to 
extract the audio and video bitstreams.  Nuvexport will likely do what 
you're looking for already, however if you don't like nuvexport, you can 
at least read through it as a guide of how to handle the fifo mechanism.
