I'm on Direct and just checked all the HBO channels. I get no indication of HDCP issues. But I may be in compliance and it wouldn't show up.
Just to point out .. you don't mean to insinuate that the OP (la_due66 in this case) is *not* in-compliant, but that there could be something wrong with the setup that is causing this problem and the user should get dish chat or call into dish to get some help ... right?
within limitations.. HDMI to HDMI, a standard cable that's 3 to 10 ft long .. the user should not be having the issue, cable going directly from TV to Dish Receiver.. etc..
To LA_DUDE66 ... no other components involved... HDMI Cable 10ft or less, directly between Dish Receiver & TV ... leave TV on ... unplug your dish receiver.. wait a minute, plug dish receiver back in and see if that clears the problem ...
HDCP is a handshake protocol backed "cluster-foxtrot" or "fubar" that sometimes gets it wrong. If the only way you can get it to work is by unplugging one component or the other every time you get the message, then you need an update ... either for the TV or the Dish Box..
HDMI is a digital medium ... cables for the most part don't effect the transmission as much (at short lengths) as does "quality" or "fear mongers" like MonsterCable would instill in people. if you bought your cable at the Dollar Thrift Store ... then maybe its bad... though it would be surprising that it only effected the handshake of HDCP and is still showing you a digital picture screen (even with the logos, you're seeing something *because* the HDMI cable connected, and such).
Do check your Mitsubishi websites and chat them if possible to see if there is a firmware update for your set (it wasn't made yesterday and even if it were, that doesn't mean the production floor had yesterday's firmware available for installing) ...
But again if you are able to get it to clear the message by power pulled reset of the Dish box, and then it doesn't happen again, then it was just taking time for the Dish Box to recognize the HDMI connection and Mitsubishi were valid destinations.
If you have *anything* in-between the TV hdmi & Dish hdmi ports.. then all best are off.. and you have to try straight between the two first..
EDIT: < WELCOME > to HDCP 101.
its a horrible class to go through.
