Has anyone experienced a clicking noise from their 1800 when changing from an hd channel to an sd channel (and vice versa) on a connected SA Explorer 8300 HD dvr? I haven't run the auto setup yet on the 1800, but I wouldn't think that would cause this problem. I had the dvr connected to the 1800 via hdmi, and then I switched to an optical connection. The problem persisted. Am I missing something?
Also, I had considered connect the dvr via component and optical to the 1800 and via hdmi to my TV. I was thinking that way, I could watch tv without the receiver on, and if I wanted to use the 1800, it would then upscale the 1080i signal from my dvr to 1080p for my tv. Is that feasible?
