Yeah, I was really disappointed when mpeg2 was chosen for the initial
atsc rollout..  I mean most of us here that are mid aged remember
mpeg4ip (vlc's parents)..  That was way back over 12 years ago...
That was stable then..  I think DVDs and the abnility to not change
encoding equipment probably helped that decision..  It's a lot like a
mythtv system.  You do not want to change too many things at once
until you (and it) are tried and true  :)

Still disappointing like you said.
