After some in shop testing, we installed our first unit in a clients home about a week ago. The system included 2 directv boxes and a panasonic bluray. Possible plan for AppleTV. One TV( 2 year old samsung DLP) had an AVR and the other(new Panasonic plasma) was standalone. Planning on adding the other 2 TV's when exercise room is finished. Plug and play out of the box with no issues. Didn't use the EDID learner as things were working ok. Runs were about 75' cat5e and terminated in 568A. Terminated to 48 port wall rack at head end with patch to matrix, TV end had RJ45 crimp on directly to rcvr with no keystone.
