I see Comedy Central actually listed 8 times as the HD is also on 110.
Am I correct that either one has 110/119/129 as a set or 61/72/77 as a set as it seems like the dish's will support one set but not both sets. And from that document I linked, it seems the installer was supposed to install something for 129 on the 500+ but didn't. Researching a bit further, it seems like the former is Western Arc and the later is Eastern Arc, are they basically the same channels. Any advantage of using one set vs the other in terms of the video and audio quality?
The HD Comedy Channels that you see on 110 are on spot beams for the Caribbean, they will not work in San Franscisco. You need the CONUS on 129 to get it in HD. Eastern and western arcs are determined by your geographic location and sign of sight. They are the same channels. The only outlier is 118 which has the internationals....
