I don't mean to come off as argumentative, it's just that your statements are the the very definition of "too good to be true" and I don't want to be disappointed. So since your statements defy logic, historical trends, and conventional wisdom, I have to ask how you could possibly know the res of both Dish and Directv, a question pondered in many threads over the past few years.
You aren't coming across "that way".
Set the time machine back a few years and what you've heard was true.
Moving to HD has caused everyone to have bandwidth issues.
DirecTV has launched 5 SATs for HD to help over come this.
MPEG-4 also helps to reduce the bit-rate with "little loss" of PQ.
Now most cable & Dish still clip about 25% of the image out and then average the missing bits back in at the receiver before it gets to your TV.
Sometimes the "average" would end up being the same bit removed, but with others it would be slightly different. "Joe Six Pack" may not see the difference.
Anyway, you question was: does DirecTV downrez their HD and the answer is: not anymore with MPEG-4.
Since "PQ" is in the eye of the beholder, it might be a good idea to compare dish & DirecTV side by side, to see for yourself.
