I have an uncommon setup. My main system in the family room is connected via component cables (long story why this is the case) and I recently decided to use the empty HDMI port to power a TV behind the wall in the guest room. I bought a long cable and cheap RF remote extender from Amazon and I was off to the races. Everything worked great as planned ..... until ..... As the guest room TV will only be used occasionally, it is mostly turned off. When I tuned in HBO on my HR21 back in the family room where the component cables are used, I received a message that my TV is incompatible with the digital content protection and I should use component cables. I figured out there must be a handshake (HDCP?) attempted on the HDMI cable and, with the TV turned off, it couldn't do it so it generated the message. After a little testing, I confirmed it. I can watch HBO (those are the only stations I've found to be a problem) on my family room TV only if I have the guest room TV turned on or cable unplugged. While this is a mild annoyance, it is something I can live with. Any suggestions how to configure this to avoid this problem - aside from switching the cabling around? There is a reason it is set up that way and I'd rather not go into it. ON EDIT: I thought of something ... if I put a powered HDMI splitter in between the HR21 and the TV, would the splitter do the necessary handshake to let the DVR continue on when the TV is off or would the TV still have to be powered on?
