I have an Insignia AV-511 receiver. It's HDMI video out runs to my TV, which has a DVI/HDMI adapter. I have my DirecTV receiver AND my Samsung Blu Ray player plugged into their respective HDMI inputs on the Insignia AV Receiver. DirecTV shows up fine on my TV, but when I boot my Samsung Blu Ray Player, it flashes a Samsung logo, I hear a start-up noise through my AVR, and then the TV screen goes either fuzzy, or totally blue. Any Ideas? Is this because of the DVI/HDMI adapter? Thanks.
