but, having said that. TV2 doesn't mean tuner 2. you can manage which tuner is doing what, but in most cases there isn't a need to worry about it. either TV output can use any of the four, since you have a K, possible tuners.
Huh. Apparently I need educating. How do you "manage which tuner is doing what" from DO or DRA? Does the answer change when you are in duo mode? I know about Record Plus (or whatever it's called) that sends recordings preferentially to one tuner or another. But what if you start up DRA and find yourself looking at a recording in progress?
