This is how it usually goes at my house...
TV1 is in the living room and TV2 is in the bedroom. Show X is setup to record and it will record on TV2. A couple of minutes before this is going to start the family decides they'd like to watch Show X on TV1...either live or after it has started (to skip commercials).
Invariably someone decides they don't want to watch Show X with the family but want to go channel surf on TV2 in the bedroom but now both TVs will be tied up with Show X. At this point it would be nice to be able to go into the Schedule, choose Show X and then Options and be able to say 'record Show X on TV1 instead of TV2' thus freeing up the TV2 tuner. Instead I have to go to TV2, bring up the guide and choose to Auto Tune to anything on in the same time slot so that,
hopefully, the recording of Show X will jump to TV1 (and you have to hurry as it is about to start
). Usually this works, but not always. Thinking about this now - the times it doesn't work may be because Show X was set up to record from TV2 originally and maybe priority rankings come into play?
There was a post a year or two ago where someone went to the trouble of mocking up menu screen shots showing how this feature might be implemented.
