I am experiencing the exact same issue in my theater room. I have even swapped out devices that I know are working properly. Ther is a 25' HDMI lead to my projector (short throw) and I assumed that the length of cable could be the issue so I purchased an HDMI signal amplifier, but no luck. My DVD player has no issues. Also, there are certain channels that I launch that crash the system and drop the configuration so I am continuously having to re-activate the device. Any help would be appreciated. Thanks.
