I meant X11 screens. For output through 2 DVI ports (assuming it doesn't
have to work for windowed playback, for which this patch does not really
work either) you just need to set things up as if you had two monitors
side-by-side or on top of each other and play a side-by-side/top-bottom
3D movie completely normally.
This even works with _any_ player btw., on Windows and on Linux (where
this kind of setup is called Xinerama).
Independent X11 screens is the Linux setup where you can't move windows
from one display to the other (advantage is it works with using completely
different graphics cards - except that that's only in theory and irrelevant
in this case since for VDPAU both outputs have to be on the same card again).
