Windows 7: three display laptop

What I need to achieve.
"dual" external spanned dual analog VGA signal at 2048x768 playing windows media video files.
One laptop display independant of the above dual spanned display.
Are there laptops that have "dual outputs" that can be spanned?



so...
1, laptop display (anything works as the control panel)
2, analog output 1 1024x768 playing high res video.
3, analog output 2 1024x768 playing high res video.
note: 2&3 are spanned, playing a 2048x768 high res video

any pointers to laptops (or hardware I can add to a laptop) that can do this would be great.
