I have a Series 2 TIVO that has been working wonderfully for over a year. I have Comcast digital cable and recently the lower channels 2-13 are very snowy to the point that watching Heroes and the Bionic Woman was painful. I've replaced every cable, had Comcast come out and measure the signal on my indoor feed and even tried an Amplifier (which helped some but didn't fix it). When I remove the TIVO altogether the Comcast channels are crystal clear like they should be. Has anyone else seen or heard of something like this before/ I'm afraid my only option now is to buy another DVR since mine is out of warranty. Any suggestions would be much appreciated.
