Thanks for the compliment and faith, however I have no experience with very long HDMI runs (my longest is about 50 feet being from the DVDO Edge scaler to the JVC projector).

There is quite a market out there for devices to extend HDMI runs using several technologies. Gefen has a decent rep and at the recent EHx show which I attended there were quite a few vendors selling gear to extend HDMI cable lengths.

As a matter of practice I use good HDMI cables but not the outrageous ones. I get them from monoprice or cablestogo and I generally use an 8" extension stub for the final connection to the component at each end so that the thick hard to bend cable is no longer a problem. I tie it, the thick cable, down to the sliding shelf that the component sits on. At the PJ I used a right angle adapter as the cable was coming down from the ceiling, but the PJ jack was horizontal.
