KenM, do you have digital cable or a satellite dish? I came to the conclusion a while ago, while looking into Tivo service for my digital cable setup, that it wasn't really mindblowing unless you had DirecTV. You could still pause and rewind, as well as record, but you couldn't do two programs at once and it didn't support hi-def recording. All of which my new Comcast DVR does do.
So if you have digital cable, I'd look into whether your provider has a DVR upgrade, rather than getting a features-crippled Tivo.
