For those that are thinking it's a HDMI handshake issue, when the C31 acts up are you able to see anything on the screen at all? Do the menus or guide or anything work? I think we may have two different issues here. For some of us, the menus/guide/recording list work fine and we just aren't able to display video. I would think if it were a HDMI handshake issue going on here, that we wouldn't get anything on the screen?
