someone else suggested that the DVD image was bypassing the
framebuffer, which i didn't follow. can someone clarify the
technical issues behind why i need to deactivate the attached
LCD display on the laptop to get DVD output on the external
display? i'm convinced it works, and now i know how to do it.
i'd just like it to not be quite so much magic. thanks.
I'm not sure about this but I suspect the video display may be using a
video overlay surface:

Typically you can only have one overlay surface per graphics device,
not per screen. As I said I'm not sure if that's what's happening for
you but it's a likely possibility.
ah, right, i remember your earlier response. i will now go
read it. :-)
