Now that I have four tuners in my new Roamio, is there a way I can I set up Season Passes for shows that may not broadcast one night, and have it default to an alternative, but not record the alternative when the first show does appear? Such as weekend news broadcasts that often get preempted. With my old one-tuner Series 2, I would just set up two or more Season Passes for shows that broadcast at the same time in order of preference, and only one would record. But now with four tuners, they all would record. Is there a trick? Or is it no longer possible?
