I would like to add that I actually found out that up to about 1024x1024
resolution -vo gl works (and with "acceptable" speed) with Server 2008
under VirtualBox virtualization, whereas vo_direct3d does _not_ work.
I admit I do not know for sure why, possibly the problem is that
hardware acceleration is requested so the init fails while it would work
as well as OpenGL if requesting software (there seems to be no "give me
whatever you have" option?).
