That is up to the copyright owners. DRM lets them dictate that HDMI only can go to a TV, not a splitter or computer, unless it is down graded to 480i and also limiting component to 480i too. Dish only looses if they do that so they won't unless someone like HBO or some first run movie on demand studio makes it part of the deal.Will the component output send an HD signal out or will it be downconverted? It seems like they've threatened to downconvert the component output in the 922 but so far as I know they never implemented that. I'm currently using component for my main TV and the HDMI is sent through Ethernet cables to my bedroom TV and I'd like to continue that, as I don't need a different channel simultaneously in each location. Mirroring works perfectly for my needs.
My video is connected to a 4X4 matrix switcher and it is HDMI DRM 3.1234(or whatever) compliant, meaning the receiver knows what devices it is sending it's signal to and the Dish signal has never stopped going through.
