Thanks, Whiskey Tango. I had a feeling that might the deal. Now, since I got my Premieres and that opened me up to automatically having HD programming, I pretty much almost record/watch the HD channels (why not, eh?).
I think I'll try to find a buyer for this Tivo and hope I can recover most of my recent costs on it (the Lifetime sub as well as the high cost of purchasing a new remote for it shortly before I replaced it). I'd love to find it a new home. It has served me well.
