Yes, I know - an unsubscribed Tivo is just a brick, but I'm thinking maybe all I want is a brick. Here's the deal: I have two S2's and one S3 so I am pretty much set Tivo-wise. I recently added a theater - with "movie only" intentions and setup - blu-ray, projector, no cable, no tuner. Now I'm thinking there may be occasions for TV on the big screen (super bowl, for example), but it would be rare. I looked for over-the-air HD tuners, but the pickings are very slim and no new products in recent years that I can find. Dusty boxes in the corners of warehouses for the most part. Then I thought of TivoHD. I'd be OK without program guide or recording - although a buffer would be nice. What do you think - would a TivoHD in brick mode serve my purposes of an over-the-air HD tuner? How about if I put a cablecard in it? Would it allow me to manually tune HD channels? Alternately, any recommendations for tuners?
