Roku player won't work with surround sound - advice?
I have a weird problem with my streaming Roku stick (3500EU running v 8.0.0.). When I connect it directly to my home cinema projector (a Viewsonic PJD7720HD), it works fine. But when I connect the Roku to the HDMI port of my surround sound (a Yamaha YHT1810) - which connects via HDMI to the projector - the picture from the Roku flashes on and off every couple of seconds indefinitely. I have tried replacing the HDMI cables to no effect. Is this a known problem, or are there any suggestions for how I can get the Roku to work with my home cinema system? Thanks, Steve
