I've just started learning what PVR's can do today, so sorry if these questions sound pretty uneducated. Is it possible to use a standalone PVR with regular TV, no cable or satellite? Is it possible to get "season passes" like they offer with a Tivo subscription, without also subscribing to some form of cable or satellite?
That was the whole idea of the stand alone units. Any stand alone Tivo or Replay can record the OTA local broadcasts. You must have a phone line hookup up to the unit (or broadband in some cases). The cleaner the picture from your antenna the less artifacts you will have.
