I have a series 2 Tivo box that I upgraded with a second hard drive 2.5 years ago. Over the last few months after the tivo is playing back for a while (well say 1 hr) the picture goes blurry to black. It seems like something is heating up then the picture goes bad. I can reset this problem by turning the TV off/on which the Tivo recognizes (my guess because a yellow light flashes on the tivo when I switch the tv off and on). I investigated the TV by playing a lot of DVD's and no problem there. I also replace the S-video cable from the tivo to the TV also not the problem. Has anyone seen anything like this before...... or is this a sign that one of my hard drives is about to through in the towel. Thank you for your help in advance
