I have checked the timers and deleted all but three of them, for the three shows that I watch. No neighbor close enough to effect it. with my house I have trouble with the UHF being strong enough to go through the inside walls, let alone the double brick exterior walls. they just seem to appear, like saturday night, I set a timer to record Nascar to TV2 and for some reason it starts recording on TV1 and then TV2 is recording more DSCHD shows. I have no clue.
I check it everyday and nothing in the timers but what belongs there and then the next day there will be 2 or three DSCHD shows recorded. I have changed the remote address a couple of times just to make sure.
Sucks cause this is the only problem I have had with the 622, except the HDMI audio drops all the time, but I switched to component anyway.
