It seems that those messages refer to the very beginning of the stream only. I
assume PSCPrefix is the PES PACKET_START_CODE_PREFIX. Maybe the PSCPrefix
message is logged for incomplete PES packets at the beginning of the stream.

Apparently TS packet 2347 is the first with the PMT. So it might also be
possible that TS-doctor complains about PES packets of yet "unknown" PIDs, as
no PMT has been transmitted yet.

The fixed file starts with a PMT packet. Could PCH be choking on the fact that
the TS stream starts right in the middle of nowhere?

Otherwise I don't see any major difference from the output of TS-doctor.
Sorry, I'm a little bit lost here.

Maybe streamdevs cStreamdevPatFilter::GetPid() filtered too much. Could you
recompile streamdev with debug output enabled:

cd STREAMDEV_SRC_DIR; make clean; DEBUG=1 make all

Plese post the debug output (sent to stderr) as well as the messages from the log.
