Read the sticky on this but not sure it's helping. My tivo was constantly rebooting itself, my menu screens were extremely slow if they worked at all. Live tv seemed to be fine. I tried the instructions on the sticky with no avail. However, when I removed both cable cards the tivo worked fine. It seemed my cards or card was bad. I called charter communications and they had me but the cards back in and they tested them and said that one of the cards was bad, but the other was fine. I have an appointment in 3 days for a replacement. Thinking the problem was solved I put the "working" cablecard in and it seemed to work fine for a couple hours, now the menus are sooo slow it's unusable. No reboots though. This has me concerned cuz they said one card was fine. Any inputs or suggestions would be welcomed. Thanks
