Advertisements I bought the TiVo HD even though I don't have an HDTV yet because I wanted to take advantage of the lifetime service transfer offer. I figured I'd buy an HDTV soon enough, but now I'm not so sure. Using the TiVo HD with an SDTV is great. I had the old 40-hour S2, and as a result recorded almost everything in High Quality to save space. I was careful not to schedule too many recordings of movies for the same reason -- I didn't want to lose recordings of my season passes. Now, with all SD programming automatically recorded in Best Quality (which looks and sounds much better than Best Quality on my S2) and the capacity to store seemingly endless hours of SDTV as well as the ability to record from two channels at once, it already feels like a whopping upgrade. Time Warner warned me that I couldn't get movies on demand with CableCard, but I can record and store so many movies already I doubt I'll miss that. (And there's always Amazon Unbox.) To anyone who's thinking of taking advantage of the service transfer even though they don't have an HDTV, I recommend it highly.
