vlc-cvs video output jerky

	Not a single one.   I did get one or two "late picture skipped" messages
	but only a couple of those out of several minutes of very jerky video.

> you've got the same problem as me.  You need to enable xvideo optimisations.  

	Of course ;)   And the Matrox G400Max + XVideo works _great_ with
	MPlayer and vlc-0.2.92 - just not with vlc-0.2.92-devel (from cvs)

	Well, uh, errr - I don't think linux drivers would be terribly
	effective or useful on a BSD/OS system <grin>

	XFree86-4.1.0 plus the Matrox provided drivers are in use though so
	I'm puzzled as to what is causing the video playback to shake so
	badly (it's only a SVCD file at that so the datarate is ~2.5 Mb/s or
	less and not even close to DVD data rates).

	I'll include the output of "vlc -v" below in case I've overlooked
	something obvious.
