Just got a new mini and was looking forward to finally using 1080p - was previously using 720p with my old mini. However, my setup runs HDMI through my amp (Yamaha 767). Handles my PS3 and bluray player just fine, but seems to choke on my mini at 1080p giving me a black screen. If I connect direct to my TV it displays ok, but then I lose my multichannel audio. I could connect up via optical (new mini has one in the headphone socket, right?) but I'd prefer to keep it all switching through the amp if possible is there a tweak to let me do this? How do I set up my resolution to be optimal? I'm confused why it wouldn't work as the PS3 outputs 1080p/60 and that is ok.
