I am betting that the hd version is the same as the sd version but in down converted letterbox version.
Even if it is Dish is still uplinking it twice on both EA & WA. Its not like locals where they can be remapped 2-3 times (like when dealing with state PBS stations where everyone in the state gets the same PBS but on different channels)
The SD is on 72.7 but the HD is on 61.5
And if you live in a EA market and dont want HD they send you a 211 as the "stock" unit and turn off the HD option in the menus
