I had D* in 05-06. I then switched to cable for a year, and now have Dish. The Standard Def was better on D*, but I see no difference in the HD quality between the 3.
That's interesting as I have had just the opposite experience,I have noticed the SD PQ is better with Dish Network and since The Krell told me that Dish Network's SD in MPEG2 is 544x480 I figured that must be the reason?.When I had D* for 3 years(2006-2009) there seemed to me that something was different but I couldn't quite figure it out but I did know that D*'s MPEG2 SD was 480x480 when I was with D*.
