Going from one Tivo box to another (P3-->P4 upgrade). Once I'm sure the Season Pass transfers (done) and recording is all working fine I want to stop the old Tivo from doing any further recordings. Other than just unplugging the Cable IN - is there a way to globally stop/pause it from further recordings without trashing the Season Passes/schedules? If I DO unplug cable IN will it just record dead space then? Or does it see no signal and use zero space? We are at about 80% full and are going to watch or transfer everything off the old box (with iTivo) in the next week or so. I just don't want it to start erasing stuff to fill with dead air or redundant recordings... Thanks!
