I can't recall if I answered with a post in this topic, but I want ESPNU HD. In fact, I have it now since I went back to Comcast. I also have my RSN in HD full time. Honestly, I expect ESPNU HD on Dish by the summer, but there is no guarantee and the summer is a dead period for college sports as far as I'm concerned. As for the full time RSN, I don't know if Dish even plans to carry them any time soon. That is especially true for an RSN that they only put up as an alternate even in SD like FS Tennessee.
I enjoyed my time with Dish, but they just didn't have a robust On Demand service or a few key channels I realized I really, really wanted. The quality is actually better than Dish with Comcast on some stations and worse on others. I'd say it is about even overall. The 2:1 QAM muxes look great. That's mostly the ESPNs, other sports, NFL, TBS, TNT, etc. The 3:1 doesn't look any worse than the 3-5 mbit/s stuff that Dish has for many channels except the MPEG2 compression tends to show pixellation rather than the blurriness, or god forbid both, that MPEG4 prefers when it becomes bit starved. I can live with that since it appears sharper on my tvs. The RSNs were particularly bad on Dish. I won't badmouth Dish though. They will improve that as they get more bandwidth. I tried it and it didn't work out. That doesn't mean they won't be my provider again in a couple of years. Hopefully by that time they have MLB Network, which I'm watching right now, by then...
P.S. Firewire recording is great too.
