HD is really becoming the pits, but I told myself years ago it would happen, just look at SD over the years.

The voom channels look worse to me, I think I was watching Equator and every time something moved it turned into blocks.

I have found that some broadcasts in HD are just poor quality (Several respective to VOOM). I'm thinking that when they recorded the program they used poor equipment thus creating poor quality HD. I also think that compression is a factor, but with the VOOM transponders I don't think they are compressing them yet.

yes they are, Voom has looked bad lately as well, lots of pixels lately.

It was very good when I subscribed to it. Maybe we should be getting a discount because of the compression. Looks like another phone call to E*;)

Is there any difference on the sat you use? I'm using 129 and some of them look really bad but others look good.

See my bitrate chart
(was last updated in August but hasn't been updated because everything is basically the same as of now):

http://home.bigsandybb.com/gmurrell/bitrate.html

6 of the Voom channels are still running in 1280x1080i HD-Lite mode, exactly how Directv sends out ALL their HDTV, picture quality is rubbish with this downconverting from the true HDTV 1920x1080i signal

HDTV quality is going down the tubes very much so, Mpeg4 is not going to change this, I wish the HDNets were on C-Band

Wow, I had no idea that all those Voom channels were only 1280x1080, I am really mad now. HBO-HD running at 9 MBPS? AHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!

I have HDNet & DiscoveryHD on Adelphia cable - I haven't noticed any macroblocking or other digital artifacts at all -- so far, I have an excellent picture.

I have been pleased with my recent switch from E* to Adelphia, not to mention that I'm also saving $30/m, or $75 overall, considering what I was paying for E* + basic cable + internet, separately.

HBO and Showtime still look good on 148. Even though the bitrate isn't much higher, I don't see the pixelation that I sometimes see on the 110 versions.

I haven't noticed any difference at all. College football today on HDNet was incredible. :)

Did you give up the Voom too Nick?Yes, I totally canned E* in favor of Adelphia's UltimateAdvantagePak + HD + an HD DVR

MonstersHD and Equator HD are just about the best channels on Dish in regards to HD, they have high bitrate and are not downrezzed, both the HDNets have high bitrate also but the HDNet channel has been pixelizing alot lately, HDNet movies is fine

6 out of the 10 vooms are 1280x1080i, the other 4 that are not look superb

DN Discovery HD version has terrible PQ compare to cable providers.
I already reported it. http://dbstalk.com/showthread.php?p=461853#post461853
Big mistake switching from cable to satellite.

DiscoveryHD took a hit on PQ just before the Olympics in 2004, when added another channel per transponder. Hasn't been the same since. Ironic, since some of their highest-rated shows (American Choppers and Monster Garage), show alot of welding shots, which are hard on MEG2 encoders and tend to pixellate alot.
