I'm having a problem with my ARCAM passing through the hi-def signal from a Scientific Atlanta HD8300 PVR. This PVR is a replacement for the HD8000 model that won't power up anymore. The problem is that the video signal is over saturating the colours. If I bi-pass the Arcam the signal is fine. I don't know if it's an issue with the newer model of the Scientific Atlanta hi-dif PVR or not. I'm not sure if maybe I should try to find another HD8000 PVR like the one that died.
