With all the dual-head experience I've had with different laptops using
ATI adapters I've found that dual head works well for regular screens,
however when doing video playback that utilizes the hardware decoder the
image will only display on one screen (lcd, monitor, or tv) with the
other screens showing a black box where the video output would be. It
looks like this may be what is happening here.
