Done - but I had to drop skiphead alltogether for some reason it
emits lots of zeros, maybe just on mpeg_packet size items. I don't
know, but just trimming expected_result and result_data in python
works and all is ok now. Updated and checked in.
Oh, and you have to include another 12 packet delay from the viterbi
decoder. 52+12.
All that was just tying a ribbon on nearly finished code - going forward
the field sync and bit timing stuff looks pretty formidable and sketchy.
It'd be nice to find the Wayne Bretl text.
