Does the cable from the multiswitch go directly to the receiver, or does it go to a wallplate, with a jumper going to the receiver? Could be the barrel in the wallplate.
Tried that with the old multiswitch. Moved it to two of the unused ports and one of the ones being used in the house with no change. didn't see the need to try it with the new multiswitch. Also I got the tech to run a dual RG6 cable to the shop this time so I can be HD ready. Both of the cables are connected at the new multiswitch and I have tried both at the receiver to see if one port was better than the other. Still no change. Thanks.
