I think you will only get TV/recordings displayed on whichever output
device is configured as the primary device. I had the same situation
with one of my setups when I had TV-out and a monitor connected
simultaneously to an ATI Radeon 9000. You can configure the TV as the
primary head (which should give you output on the TV for LiveTV and
recordings) and the monitor would not have the video. Completely
disconnecting the monitor enables the video driver to detect the
connected TV and use that as the primary device with no other
configuring that I remember (other than TV standard to use etc).
