Update: Dish sent a tech this morning, replaced the 922, tv1 & 2 worked fine on the modulator, after about an hour the receiver stopped responding to the remotes. I did a front panel reset, after the reboot no tv1 on the modulator! I checked the mod settings, everything still there. So I did a power cord reset, same results. I then did a factory reset, changed the modulator settings back to 90 and 92 and still no tv1 on the mod. Does anybody else use the tv1 mod output on their 922? Or am I the only guy? Dish CSRs don't seem to know about the tv1 modulator output (it must not be in their script). Maybe a dish rep here has some ideas? Thanks in advance!
