Use Xine's "Xshm" or mplayer's "x11" video output plugin.  Xine is 
almost certainly using XV, since XV is faster than XShm.  Most video 
cards have only one XV overlay, and that overlay is locked to the 
primary display device (LCD on laptops) unless you put some 
video-card-specific option in your X config file to lock the overlay to 
the secondary display device.  Some cards don't have that option.  Read 
the man page for your X server to find out if that option is present if 
you really want to use XV on the secondary head.

This is a pretty common question and has been asked and answered 
frequently on comp.os.linux.x .  HTH,
