[mythtv-users] Video studder XvMC w/OSD

[Mitch Gore]

Hi,

On my frontend I have a bad issue with XvMC and HD video.  When watching HD
and the OSD comes up I get very bad studdering.

I have tried everything in the XvMC wiki and cant get it any better.

The FE:
3.0 GHz P4
nvidia 6200 w/ component out
diskless

When playing HD i only see ~50% use and when the OSD is up it uses the same.

My Xorg.conf:
[root at mythfe ~]# cat /etc/X11/xorg.conf
# Xorg configuration created by livna-config-display

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

        ModulePath   "/usr/lib/xorg/modules/extensions"

EndSection

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us+inet"
EndSection

        Option      "NoLogo" "true"
        Option      "UseEvents" "True"
        Option      "ConnectedMonitor" "TV"
        Option      "NVAGP" "1"
        Option      "XvmcUsesTextures" "false"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        Option     "metamodes" "CRT: 1280x720 +0+0"
        Option      "AddARGBGLXVisuals" "True"
EndSection

Section "Extensions"
        Option      "Composite" "Enable"
EndSection

I have tried changing Sync to Vblank setting but nothing seems to help.

Thanks,
Mitchell
