Good news and bad news...I installed the rack on the loft, ran the cable, and hooked up all the equipment.
The bad...
1: ARC will no longer work.
2: OPPO is no longer seen by my Samsung, Yamaha, or Pioneer units either(For control)
3: OPPO will not even transmit a picture to the Samsung 4k tv although every other piece of equipment will transmit picture, and sound.
The good...
Both the PS3, and the Xbox one work fine...including the controllers from the MLP.
I spent most of yesterday resetting to factory the Yamah, and the Samsung with zero results. I tried different cables for the OPPO with zero results too, so today I ordered a fiber cable that was on Amazon's lightning sale. I got a 30 meter ( I only needed 75 feet, but the next size down was 20 meter). I picked it up for $170 delivered to my Texas address. I will have to pay another 17% on top of that due to duty, but hopefully this will solve the problems. Here is the cable I bought...
