Advertisements I've read multiple threads on this and I'm still confused so hopefully someone can help. I've currently got three Tivo's: one with lifetime and two with MSD at 6.95 a month. I've just purchased (from Amazon) a new HD. I want to retire one of the monthlys and go monthly on the new one as well. What's the cheapest way for me to do this? If I simply add the new one and drop one of the old ones do I still get the $6.95 rate on the new one? Or do I need to add the new one by changing the service number on one of the existing ones? If it's the later, is that all that's required to "activate" the new unit? I'd appreciate any input.
