The Flexcop handles the MpegTransport Stream.  It is not a "subset MPEG
decoder".  The flexcop can filter up to 38 PIDs at the same time.  This means
you can record more than 1 station at a time.  If you exceed 38 pids then you
are in trouble.  Most channels will be 2 PIDs (Audio + Video).  So you do the
math.

All digital TV cards do not do anything with Mpeg.  They are simply transporting
a datastream.  It could be anything they send, it just happens to be Mpeg we use
it for.
