I installed an OTA module into my 922 today and need some info on how to set the rf modulator output to either channel 3 or 4. When I go to the modulator settings screen I only see the TV1 and TV2 choices. Also is there any way to have the OTA scan digital cable channels? I spoke to a Dish tech rep and he told me all of the info in the OTA manual is not valid for the 922 and that the SD rf output on the OTA module does not work. I gues I wasted $50 because I wanted to feed the SD rf to my old TVs in my house. Any info from 922 owners who also have an OTA module would be appreciated.
