Proposed fix

In the CableTV industry, may headends push out MPEG2 transport streams
compliant with the Motorola DigiCipher II proprietary standard.  tsdemux
handles these streams fine with one exception, the MPEG2 video stream_type in
the PMT for these streams is 0x80 instead of 0x2.

There is currently a conflicting stream type in the BluRay program stream types
(ST_BD_AUDIO_LPCM).  I used the packet size (BluRay is only 192 M2TS packets)
to be able to choose between them.
