Topic: Because there are SATELLITE SPECIFIC newsgroups (rec.video.satellite.*)
which are more appropriate.
Signal: Because DirecTV uses its OWN proprietary version of MPEG encoding
which is neither MPEG2-DVB or DCII; it is incompatible and therefore these
other formats are not recievable by a DirecTV satellite system. If TNT-HD were
to be available via DSS, it would be a second-generation signal (i.e. received
by the ground station in the other format and converted to DSS). Although for
digital TV, that doesn't matter as much, why not receive it DIRECTLY in its
native format?
