IIRC, there are some fundamental problems with the PES packetizer.
I've observed that some frames were not wrapped in a PES, which is
MPEG compliant, but it is not recommended, since most STBs relay on
the PES header.

The PCR values looks correct now, but since some PTS/DTS values are
missing/incorrect, there are some buffering issues i've noticed.
One thing I've noticed immediately is that there are no null (pudding)
packets - not in VBR nor CBR streams.

This should be an assert, IMHO.
