[PD] [Gnome/Ubuntu] Gem video on external screen

Hi all,

Im a bit desperate to find a way to play video on an external screen
without Gem (or even X/Gnome) crashing.

Ive set up xorg.conf to a virtual screensize of the double
horizontally so as to have a projector read the video from the "right
part" of the screen, and still have my GUIs visible on the "left part"
(what is visible on my laptop screen).

This is how it looks in xorg.conf:

Section "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation Mobile GM965/GL960 Integrated Graphi$
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Depth 24
                Virtual 2048 768

The CPU jumps to 60% when playing video with the external screen on,
but lays nicely on 8-9% when only playing on the normal screen. I
guess lots of people are working with similar stuff - are there other
(more stable/safe/efficient) ways of getting to this? or is the high
CPU something to expect when using an external screen?

Are there any good ways of finding the source of Gem crashes btw?

Im very happy for any feedback as Im quite fresh on both Gem and projections :)
