Not exactly.... Its a little known fact that any time a source is powered up, like a DSS receiver, blueray, etc., it calls out the HDMI port to see whats out there. If there is a device that can convert the digital protected stream into something like HD-SDI (pure uncompressed video), it will shut the port off because you now have the potential of removing the copy protection, so you must be a bootlegger.
Whats likely happening is that when that bootup call is performed by the receiver, either its getting two responses from both receivers, or a corrupted response because there are two TV's trying to talk at the same time. I see this occasionally in the RV and the only fix is to repower the receiver and let it try again so the receiver only talks to one TV. Leaving both on at power up is likely causing the error. In DirecTV land they turn HDCP on and off at random. We see it at the station when plugging in HD-SDI converters and get a bluescreen. We can usually call and get an exception, but a normal customer service doesnt have that authority nor likely understands the protocol.
