The HD DVRs have multiple outputs on the back of them that are all live all the time.
HDMI, Component , Composite and S Video.
Running another connection to the DVR will "Mirror" the second TV to the first ( both TVs are on the same channel all the time ).
Use of the Composite and S Video connections will cause the TVs to drop to SD resolution.
Using the Component connection to one TV and HDMI to the other can cause HDCP problems with some of the Premium channels like HBO.
Using a powered HDMI splitter will allow you to use each TV with HDMI connections.
