Hi, I know the OneGuide is not supported yet in Canada but I did connect my Cisco430 STB to the HDMI in. It works perfectly with HD Channel but it freezes when you switch to SD channel. We do not have an SD override as far as we know in the STB. The box is setup to display in 1080i at all time. I did try 720p same result. While the image is frozen the STB is still responding which mean I can switch back to an HD channel and its working.
Something is happening between the Xbox TV apps and the STB in the negotiation of the HDCP protocol. The client on the STB is mediaroom(previously owned by MS) so you would think it would be compatible. Any kind help would be appreciated.
