I just sent the following email to dishquality@echostar.com:

I notice a degradation in picture quality on the following HD channels:

9425 NFLHD
9429 NTGHD
9435 STZHD
9461 HGHD

There are terrible motion artifacts and lots of macroblocking. The picture on STZHD is very soft and lacks the picture sharpness that SHOHD and HBOHD have.

Could my observations be caused by the fact that these 4 HD channels share the same transponder on the 129 satellite (#30)? All the other HD channels on 129 are three to a transponder. FDHD, channel 9462 is on it's own transponder and the picture quality is much much better. Could this be caused by overcompression or insufficient bandwidth to support 4 channels on one transponder?

I look forward to your response.
