Actually, the CPU bit is not true. Its at 50-60% regardless, sorry for the noise.
Still though, I guess the main issue is that Gem crashes upon loading videos into pix_film. Anyone know a way to track the reason for Gem troubles?
cheers, Martin

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).you will probably need to set xorg for two separate displays, and one
of these can be 3D accelerated, I usually start pd with Gem from the
display with the projector, and control it with another pd started on
the other display. This has worked well with 4 screens from 2 NVIDIA
cards uswing debian, I guess it would be also ok with an intel
chipset, as it does not rely on twinview or any other fancy graphics
stuff. Alternatively I believe Gem can open a gemwin on a different
display to the one pd was started on, check the list archives as I
have not tried this.if you have to separate x displays running, you can start pd and its gui on the first screen and by sending 'create :0.1' (or whatever id the second display has) to [gemwin] you can create the gem window on the external screen/projector.
wouldn't it be nice to have this in the documentation as part of the gemwin-help [pd window properties] subpatch? greets olsen
i made different experiences with different video cards. with an ati radeon mobility 9600 i was only able to have 3d acceleration on the first head. with several nvidia cards i managed to have hardware acceleration running on both heads. you probably find more info about how to set up 3d acceleration on the ubuntu wiki. gem should print something like 'GEM: Direct Rendering enabled!', when you start the rendering, if 3d acceleration works.
