OK, I'm clear on how it works now. Do you have a description of the packet
format of the AV stream? I can figure it out from the ps2avpes program,
but it's going to take me a lot longer than if I had something describing
the layout. Also, if you want to give me what you've got so far for going
from AV_PES to PES, I'll be happy to tweak it and try it with a few
hardware decoders I have.

Terry.
