Help connect MAC6700 receiver to cable

[surrounded by sound]

Before I broke down my system to move I was able to watch my LG smart tv (hulu & netfix) through my MAC6700 receiver with no problems. Now when I try to use Hulu & Netflix through the receiver I only get audio from the cable box. What step reconnecting have I missed to watch correctly? I have the cable from the wall to the box, hdmi cable to tv, and rca left and right to aux. connection on the receiver. And for some unknown reason the tuner selection on receiver screen went away. I am unable to listen to the radio. I emailed Chuck Hinton but he didn't know how to correct it. Thanks and Have nice 4th.

I'm assuming Netflix/Hulu apps are in the TV opposed to being included in the cablebox. You need to run a digital connection from your TV to the 6700. In this way you really wouldn't need the RCA connection from the cablebox, everything played by the TV would output digitally and be decoded in the 6700.
