Have you been paying attention?
Dish didn't move SD's around on 110.
I indeed remembered incorrectly (partially because the HD move was a couple of months ago).
However, I think this characterization is incorrect.They downrezzed and bit starved the MPEG2 HD's on 110. 4 MPEG2 HD's per TP!
Think about it... they killed the quality on the programming you pay for to put up PPV's DirecTV has a better looking DiscoveryHD Theater right now.
I had a recording on my 622 of one of the better looking HD-Net programs (Rick Steve's Europe). After the changeover to more MPEG2-HD channels per transponder, I spotted the same episode being shown again, and recorded it.
I spent quite a bit of time going back and forth between the two recordings, examining different details - water, faces, buildings, etc. - and couldn't find any difference. At one point, I thought I spotted a little improvement in one version - but it was very subtle, and I could have been wrong - and when I pressed "INFO", I found that the improvement was in the later recording.
At the bitrates necessary for real-world satellite and cable providers, downrezzing improves PQ, otherwise it wouldn't be used.
PS I'm watching Rave-HD right now, and you can see the tiny beads of sweat sitting on top of her face makeup. You can see imperfections in the varnish coating on the bass, and small variations in the corrosion on the brass. And - a really difficult test for encoders - the wisps of smoke from her cigarette are perfectly reproduced. If this is "HD-Lite", we need more!
