some information about my system

have a look at https://bugs.launchpad.net/bugs/460616 and http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#the_Virtual_screen as well

The i915 driver does not seem to have Xvideo support for a virtual screen extending beyond 2048 pixels in either dimension.  Such a dual-head setup will play the audio track but not the video of an avi file, for example.

Test case:
dual-head with i915 driver, I use a netbook with internal resolution of 1024x600 and an external display with 1680x1050. Stacked on top of each other in dual-head configuration (600+1050 < 2048) the video will display fine.  When side by side (1680+1024 > 2048) only a black square is shown instead of the video.
