I seem to have a connection problem. My Thompson digibox is connected by scart direct to the TV and also by scart to the video recorder. The Video recorder is connected to the TV through an S-Video cable. (A DVD Player is also connected direct to TV by scart). The digibox plays perfectly well to the TV as long as the video recorder is off. As soon as I turn it on the signal is interrupted by what I assume is some sort of video feedback. Any easy solutions?
