My Comcast bill list the Comcast DVR cost as $9.95/month so when I got my Series 3 working great I was going to use a HD Cable box on another HD TV in my home. I thought that I would save $9.95/month by not having the DVR function, not so, its only a savings of $4.95. That means that if you have a HDTV and A HD Cable Box, to upgrade to a HD DVR the cost increase would be only $4.95/month. That is less than I thought. My location is in the Hartford CT area. I mention this because it tells me that TiVo really needs that lower cost HD-DVR that I have been hearing about.
