"The Tivo box has detected a serious problem and is now attempting to fix it" on a green screen. It claims it will take three hours to fix. From everything I've read here, the problem is usually a hard drive issue on a Tivo that has a hard drive - which the Mini does not. So what does this screen mean on a Tivo Mini? It hasn't been three hours yet so I don't know if the problem really does get resolved in three hours, but I'm puzzled by what might be wrong since there isn't much to a Mini that could fail, and there doesn't seem to be any information on this problem occurring with a Mini. Any ideas?
