I have a 722k and I've been confused by this thing's recording features. I've looked for answers but haven't gotten a clear one. I want to record to a specific tuner (TV1 or TV2), but even when I set up my timers from TV2 with that tuner selected they still won't allow TV1 to switch channels while it's recording (and this is when just one thing is recording on TV2; I haven't even tried two things). Record Plus had been enabled and the preference was set to TV2. Does it need to be disabled? Or set to TV1? So can I get a clear breakdown of what I can and can't do with a 722k? I want to be able to record one thing on one while being able to flip channels on the other. That's not much to ask from a 722k. I'm not even asking to be able to record two things at once. I know I can do that on TV1 if I don't watch or change one of the channels. Is recording two things at once possible on TV2?
