As I’ve mentioned before we have a TivoHD PVR unit and we LOVE it. It’s one of the few things that we give an unqualified recommendation. It’s great. Best in class. You won’t regret the purchase.
However, one thing that TivoHD can’t accommodate is pay-per-view movies. It’s not so much that Tivo can’t handle it as much as the cable companies don’t currently have the infrastructure to do pay-per-view for any cable card device. It requires two way interactive cable cards that aren’t yet rolled out. This is a bit of a drag since my wife used to use pay-per-view enough to make me wince every time I saw the cable bill.
