A few days ago my tivo (series 3) started acting sluggish. It would take a while to pull up Guide information, change channels, access shows, etc. Today it won't do anything. I recycled the power several times and it goes through the "Just a few more minutes", the THX sound and then gets to a blank orange screen with the little search lights. I think this is the background for the main screen but it's totally empty. It won't go beyond that. Does this just mean my HDD ate it? Are the first few screens running from memory instead of disk? Or is it something else I'm missing? Thanks in advance.
