HDMI and Uverse

[radagast]

I have a question about HDMI. Please no speculation. Just those who KNOW.

I had Comcast HD until this morning. Comcast's HD box had a DVI output. Uverse was installed. The Uverse HD box has HDMI. Now I have sound, but no picture going into my DVD recorder. I am using the 3 analog RCA jacks for video and 2 channels of audio coming out of the Uverse HD box. I called Uverse and they told me that it is the standard to disable any other video outputs when HDMI is being used. I disconnected the HDMI from the Uverse box and sure enough there was picture.

Is what Uverse telling me BS about the HDMI standard?

Uverse is correct. HDMI output will use the HDCP standard, which only allows one display to be used at a time - no splitters on the HDMI cable, and no other video outputs can be enabled for a second display.

Another example is on home theater PC's - even if dual displays are connected to the PC, HDMI/DVI output can only go through one output.
