Nvidia Screen tearing with Xv
 
So as stated I have really bad screen tearing while using the Xv rendering mode in both xine (primarily what I use) and mplayer. I have sync to vblank checked but it doesn't make a difference. In OpenGL mode there is no tearing but then I can't get the on screen display, and thus no subtitles either.

I'm running Slackware 12.0 with the 169.07 drivers using an 8800GT. I'm not using XGL or anything either, just a basic install for the most part.

Here's my xorg.conf if it is of any help.

Code:

Section "ServerLayout"

# The Identifier line must be present
# Each Screen line specifies a Screen section name, and optionally
# the relative position of other screens.  The four names after
# primary screen name are the screens to the top, bottom, left and right
# of the primary screen.  In this example, screen 2 is located to the
# right of screen 1.
# Each InputDevice line specifies an InputDevice section name and
# optionally some options to specify the way the device is to be
# used.  Those options include "CorePointer", "CoreKeyboard" and
# "SendCoreEvents".
