[mythtv-users] Posterized S-video output

I'm running 0.20, and I've noticed that the S-video output from my  
NVidia GeForce4 MX 440 AGP 8x is posterized, like it's set to 16-bit  
color instead of 24-bit. It's especially noticeable in the menu  
background in the Titivillus theme (there are 7 distinct diagonal  
blue bands instead of a smooth gradient), but I'm pretty sure that  
it's also the cause of muddy shadows and general blockiness in the  
video playback as well. The output from the VGA port doesn't exhibit  
the posterization. I've tried adjusting all the settings in the  
nvidia-settings control panel, without any improvement.

I have an MVPMC that displays an absolutely gorgeous picture from the  
same recordings, so I'm pretty sure that it's not my capture card  

I'm using the nvidia drivers from the atrpms site on Fedora Core 5.  
Is this a limitation of my video card, a problem with my drivers, or  
what? If it's just my card, does anybody have recommendations for an  
inexpensive replacement?
