Hi, I am new to this board...I hope you can help me out.
I just got a refurb Series 2 from TiVo after my original unit started randomly freezing up (video and audio, remote non-responsive) over and over again. Finally the original unit put up a green screen that said "TiVo has detected a serious problem and is attempting to fix it...this may take more than 3 hours." It never worked at all after that...random re-starts, freeze-ups, etc. Now my replacement box is doing the same kind of freeze-ups. Any ideas?? TiVo support didn't seem to have any. It's running with a Comcast digital cable box. Using phone line, not networked. My other TiVo unit (also with Comcast digital cable box) has been running fine.
