Fixed.  Some of the PES packets have a non-zero PES_scrambling_control
field, and the demuxer was throwing those away assuming they were
encrypted.  That's not the case, so I've removed that check.  All
non-zero values for that field have unspecified meaning anyway, so
doing anything at all based on that value doesn't make much sense.
