[mythtv-users] Video frame skipping

[Paul]

I am getting more frequent frame skipping with my system both in SD and 
HDTV.
I have switch to hd480p to improve this somewhat.

what to do,now as I have googled the mailing lists and updated my 
settings  to this and that.
I've added this to my "Device" section in xorg.conf
        Option      "XvmcUsesTextures" "true"
        Option      "UseEvents" "True"

 .nvidia-settings-rc
0/XVideoTextureSyncToVBlank=1

I have a CPU AMD3200  with Nvidia 6200TC

 I have recently updated to Fedora8 and MythTV 0.21, and latest Nvidia 
driver (169.12) and I'm unsure which of these upgrades as caused the 
problem as I have little problems with this on FC6 and Mythtv 0.20

I have seen a similar thread some where but no resolution.
