Sand that is totally incorrect, there are bitrate charts over on the programming forum
HDnet Movies on directv right now is 8-9 Mbps reduced 1280 Horz.
HDnet Movies Dish is 16-18 Mbps full 1920 Horz.
Directv is compressing and downrezzing HD to Hell and back
Guys Dish Network HD is so much better it is not even funny, I have had both for a while, I had my whole house filled with directv and bought 1000$ HD receivers, I sold my entire Directv setup because of the low quality of their HD channels, they are just unbearable to watch
One the other hand Dish Networks HD is worlds better, just recently they have started putting 3 HD channels per 8psk transponder and the quality has went down slightly mainly DiscoveryHD, but I am fairly certain that Dish will get everything fixed, Dish has always shown more respect to HD, at least in the past, I cannot gurantee what they will do in the future
Hdnet is so much better on Dish, it's not even close, HDNet and HDnet Movies are on one 8psk transponder all to their lonesome on Dish
I am also 99% certain that they do not downrez their HD, they send the full 1920x1088
ShowtimeHD is also much better on Dish
With good quality HD and my 921 I am really happy
I use a Barco Data 808s on 106" 1.78 screen
