[MPlayer-users] Radeon Vidix: Not synchronised with VSYNC?

I'm using a PCI Radeon 9000 with a VIA Eden-M10000 with the 1GHz Nehemiah C3
processor. The Radeon 9000 is driving a 1600x1200 LCD at native resolution
over DVI (ie, at 60Hz).
I am running MPlayer (setuid root) from CVS as follows:
mplayer -v -vsync -fs -zoom -double -vsync -slave -ao oss -vo fbdev:vidix -cache 8192 -vop pp=0x20000 -aspect 16:9 /video/vcr/20030730-2058-ER__Foreign_Affairs.mpg > /dev/null 2>&1
I am seeing "tearing" between frames -- it looks like the frame flip is not
synchronised with the vertical refresh.
I see the same effect with -ao null, so it is not a sound driver issue.
I see the same effect without the -fs, -zoom, -slave and -vop options.
CPU usage is around 66% during playback.
Does the Radeon VIDIX driver not support synchronised frame flipping? Can
anyone suggest an alternative solution to achieve this?
Thanks in advance!
