I've got two HR-21s currently (4 tuners). I'm getting an HR-34 installed today, so I'll be up to 9 tuners. One of the HR-21s will only be in service long enough to watch the rest of the recordings on it, and I'll cancel all the recordings in the schedule as soon as I get them programmed into the HR-34. What's the best way to make sure I don't have any problems with the SWM-8 and the HR-34? Can I just go into setup on one or both of the HR-21s and set them to single tuner?
