I am trying , with my new 622, to record one channel and watch another on TV1 and let my husband watch wataever he wants on TV2 (which would be a 3rd channel). can't seem to do that. I can do the TV1 part, but husband can't change his channel without cacelling my recording. Selling points about 622 says "watch and record on both TV's" If you have to watch what you are recording, there doesn't seem to be much point. Or am I doing it wrong?
