Thanks for your reply Andrew
I don't think so. I've been through the manual a few times and can't find a reference to it yet. If you think it would be a pain I may just have to send it back and get one with analogue outs.
It's a yamaha rxv1600, so if anyone does know if it is possible to pass a 1080p signal and in a blind panic I have just overlooked something. I would be very grateful if you could let me know.
Cheers
