I'll try and stay brief. If this is in the wrong forum please direct me elsewhere, thanks. Was away from home for 2 weeks and came back to discover the Tivo acting very slowly. The menus lagged and the playback, live or recorded, does not work properly. Our cable is working on another Tivo (Series 2). I took out the cable card and Ethernet connection and playback of recorded shows works for 6-9 seconds before pausing for a few and then playing 6-9 seconds and so on. I should note that the unit has always seemed very buggy, but I took that as a software issue. Tivo support suggested getting a replacement for $150. I have a lifetime service on the unit which I was told was still good after the replacement. 2 questions (maybe I should be asking better questions but these are the ones I have): First, is the the HD failing and can I swap out a new one? Second, is there another way around getting a replacement unit like resetting the Tivo? Any help is appreciated!
