Ok, lets think about this here for a second. If you are going to use the one for all remote you bought in the main room,then how could you/why would you use that remote in the main room and the second room at the same time? in this case the factory UHF remote should be fine, so i don't think this is our plan.
If your not planning the OFA in your main room, and bought it instead for the second room, then you probably didn't realize that dish remotes are UHF not RF. Besides even if they were RF (like some Directv remotes for example) these Rf factory remotes typically use a proprietery frequency that none of the aftermarket remotes work with.
So if you are wanting to have a programmable remote for the second room that controls the TV2 and your tv/dvd/etc in your second room, then you have to use 2 remotes until dish changes the software to have IR codes for TV2 for us. Then you could get a universal remote that has a remote Rf receiver that could output IR to the 522/625/942 (what ever your working with). I personally think dish should just pick a code set say address 5 and assign the 522/625/942 to respond to UHF, and IR code set 5 for TV2. That would give us much better control options.
As far as I know, the 522/625/942 only accept UHF for TV2, unless the current barrage of software updates has addressed this.
