anyone having issues with this receiver? First off it's slow response time. Meaning you change a channel and it shows the banner at top like it changes channels, but takes 7-10 seconds to see a picture. Second and most aggravating. Using a Metra brand hdmi extenders over cat5. The audio will not work. I can use another source over extenders and audio works. Setup: dish 100.4 eastern arc. 3 lines (185 feet) to a dp44 switch. 4 - 211z receivers. Switch and receivers in equipment rack. Each receiver is connected to a Metra brand HDMI Extender over cat5. Attached to LG tvs. Also using Control4 to control all.
