Very odd HDMI issue here in a somewhat complicated setup.
One end of the house (I'll call "AV Rack") has an HDMI 8x8 matrix switch. Everything running beautifully on it for years, and it feeds into Gefen baluns, in particular to one room far away I'll call "Basement". The Basement with its Hitachi TV has worked great.
That room has bunch of local HDMI-based stuff in it as well. So, the HDMI feed from the AV Rack goes into input1 of a very inexpensive 5x1 HDMI switch, which also has a Boxee Box in input2, a Wii (via Component/HDMI converter) in input3, and xBox 360 in input4. This all has worked beautifully for ya year: I could get input from any of those four sources displayed on that TV. Again, works great.
I replaced the TV I had (it broke) with a Samsung 8000 series TV. Again, everything works fine. The new TV is not an issue.
Now, I plug in a Samsung Blu-Ray-based "Home Theater" (HT-E6730WZA) into the one free port on the 5x1 HDMI switch. Just the fact I plug the Blue-Ray HDMI Output into the switch means the TV will no longer properly display input from the AV Rack (via the Gefen). It will display input from the other 3 devices: xBox, Wii, Boxee Box, just fine. But for the input from the AV Rack, it constantly jumps the image, has dropouts, etc. This interference continues until I unplug the Blu Ray player from the 5x1 switch - the moment I do that, the image from the AV Rack stabilizes. I put it back in, and the input from the AV Rack is messed up, no matter what I do. So, I try plugging the Blu Ray player and the AV Rack HDMI into the TV directly - bypassing the 5x1 thing. Same problem. AV Rack input works fine on the TV, until the moment I plug the Blu Ray into the TV. When that happens, messy AV Rack images. Unplug the BluRay from the TV, and the image from the AV Rack is fine again. All this time, the images from the BluRay player are wonderful. It's just the AV Rack image that is messed u.
My workaround is to constantly plug in and out the Blu Ray cable, based on need. Ick.
Does anyone know in the world is this happening? It's quite annoying!
