I've got an HD Tivo hooked via component to a Panasonic LCD TV. Periodically (frequently!) the picture will black out for a second or two and then return. The sound stays on the whole time. If I rewind and play it back it happens in exactly the same places, and if I have something recorded it can still happen. It happens on both HD and SD programming. It's driving me bonkers, but I don't know if it is the TV or the HD Tivo. I know that the HDMI had all sorts of sync issues, but I've never heard of this type. Any opinions?
