That happens to me a lot with evening football games, while two things are recording on the DVR connected to the TV that I want to watch.
Rather than changing rooms, I just record the game on on one of the other DVR's and watch it on the TV that I wanted to watch it on in the first place, while it's recording.
That works too, but once I drag my lazy self into the next room it's just as easy for me to watch it there as it is to start the recording in the Family Room and go back to the Living Room. In fact it's probably easier.
And it's not like the Family Room is a bad spot. In fact the TV in the Family Room is a 58" plasma as opposed to the 40" LCD in the Living Room. I just happen to be a very "Newtonian" person. You know. An object at rest tends to remain at rest until acted upon by an outside force. That's me in a nutshell.
