I am thinking of getting an HDTV which means I have to upgrade to HD tivo from the series 2. Reading this forum, it looks like I need to try to convince comcast to give me 2 "cards" so that the dual tuner function works. Is this correct? Will they really fork over 2 cards knowing full well that this competes against their own DVR? On another note, i saw that there was a mutli tuner card available but that the Tivo HD is not compatible with this until November? A) Does comcast have this multi-tuner and b) does this mean I shouldn't by the tivo HD until it November when it comes out?
