I have Directv D12-100 box and trying to connect to M1 slingbox. We've updated to U-verse and using a hard line cable to slingbox. But the video shows to connect the cable with 5 wires but on the standard (not HD) D12 only has 3 connection spots (video out -yellow, audio -white and audio-red) and on the M1 slingbox there are several with the same color connection spots. My question is how do I connect the 3 connection from my Directv receiver to the M1 slingbox. When we disconnected the wires from the satellite receiver and not slingbox connect it the same and still no video. It keeps saying to check cables. I'm lost.
