Why does 129 look better then 61.5 (PQ)?

[JoeSp]

All the new HD recently motivated me to move my 61.5 dish to pick up 129. Both my wife and I have noticed significant Picture Quality improvement along with a noticable improvement in the sound quality too for HD being received from those satellites. Since both sats are broadcasting HD in MPEG4 -- why the improvement?

I tend to agree, but I'd also like to see a bitrate and transponder comparison of the two satellites. Does Dish uplink virtually identical information to both satellites or are there compromises? I've also heard the exact opposite opinion of this forum about 61.5 looking better. That makes me pretty sure it is all perception.
