My current AV setup went live in early 2010. I use an Octava 4x4 CAT5/6 HDMI Matrix in the basement to transmit A/V to my main and bedroom TV I have a couple year old Hopper and two Joeys. The week of July 4th (On like July 2nd) My TV's that go through the Matrix started having issues connecting to the hopper through my current (and assumed stable) setup. I'm getting "no signal", then a green screen w/sound, and eventually picture and sound. Once it's working it appears to be stable. I'm currently waiting on a call back from Octava, but was wondering if anyone has experienced similar issues (with or without extended range connections) since the beginning of July. For example, my main TV also goes through an AV receiver, and when I turn it on/off I have to endure the no signal/green screen/signal cycle. It would appear that is is directly related to going through the matrix as my Joey's connect fine w/o any green screen. At both TV locations I am experiencing the same symptom as well as with a 3rd TV that I lugged to one of those locations to test with. My best guess is a Handshake/HDCP issue, but any insight would be appreciated.
