Well, I know now that my mplayer/.config was the cause of it not playing in 
it's own space. I used vo=gl2,xv. xv is the one that plays in the designated 
space.

However, I've got problems too, if I use the stop command or go to another 
page while the plugin is still loaded - gdb shows:

Url: http://www.apple.com/trailers/fox/x3/
Action: click one of the HD teasers then click stop:

Action: click medium on the 'normal' trailers, play it, stop if you want, then 
click backbutton:
