Here is my set up: I have the 811 running through fiber (TOSLink) to my Sony A/V Receiver. I have a fiber and coax input under DVD/LD on my A/V Receiver. I have my DVD player hooked up with coax to my A/V Receiver. When I had the 510 and 6000 hooked up to it as long as my DVD player wasn't on the sound would be fine. Visa Versa when the DVD player was on and the Sat receiver was off the sound from the DVD player was fine. For some reason with the 811, it will not release the sound output even when turned off. I mean, there is no sound, but my A/V receiver will not switch from Opt to Coax like it did with the 6000 and 510. The only work around is to unplug the fiber cable from the 811. DISH Tech support (actually advanced tech support) had no clue (as usual) and thought the 811 was bad. They are sending a tech out for Sat the 13th. Already not happy about the other issues with the 811 and now this. Has anyone else had any issues like this?
