[mythtv-users] Anyone have non-crapy svideo output?

I'm still struggling with some video output issues with an old GeForce
("nVidia Corporation NV18 [GeForce4 MX 4000 AGP 8x]") and the nvidia
drivers. Among my challenges, lateral pixilation on movement (panning or
fast cars and base runners), and a failure of Xv to adjust hue etc.

I'm wondering is I should steal all or part of this config to try it. Here
is my current xorg.conf:


# Xorg configuration created by system-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/nvidia"
        ModulePath   "/usr/lib/xorg/modules/extensions"
        ModulePath   "/usr/lib/xorg/modules"
EndSection

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

Section "Device"

        Option "RenderAccel" "1"
        # TV Out Setup
        Identifier  "Videocard1"
        Driver      "nvidia"
        Option      "UseDisplayDevice"  "DFP-0"
        Option      "TVStandard" "NTSC-M"
        Option      "TVOutFormat" "SVIDEO"
EndSection

Section "Screen"

        #Device     "Videocard0"
        Identifier "Screen0"
        Device     "Videocard1"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "800x600" "640x480" "480x360"
        EndSubSection
EndSection
# end xorg.conf

The TV is a generic boob tube (not fair -- it was state of the art a few
years ago) and I haven't run any utilities on it to dump a mode line.
Except for the hue and pixilation, all is well, and I don't want to screw
anything up.

I've been around Linux a while, but I'm an apps programmer, so I'm a
little out of my depth here.

TIA,
