DirecTV's bit rate for MPEG-2 SD programs is also about 1 GB/hour.  It may
be higher for "important" channels like HBO, or lower for less important
channels like Comedy Central.

This level of compression tends to be OK for a tube TV, but shows much more
artifacts on a modern HD set.

You can believe that Comcast, DirecTV, and everyone else are relentlessly
compressing these shows until they confess.  :)
