[mythtv-users] Svideo Tearing

While mplayer SD video as viewed on my CRT is excellent, I get 
tearing during fast pans in clone mode viewing SD video through 
svideo-out on a standard TV.  I have the same results with both a 
GeForce FX 5500 and GeForce FX 6200.  I have tried repeatedly to get 
a single response from the Nvidia support forum but have been 
unsuccessful to date.  I have a WinTV PVR 500 capture card and the 
mpg files it generates are excellent.  This has been proven by 
watching the video on a Windows box using Windows Media Player and a 
Samba mount of the file.

I need to demonstrate to my spouse that my MythTV investment is 
worthwhile.  The tearing annoys her and while the video quality on a 
PC is excellent, watching shows using Tapeworm on her PC will not cut 
it for her.  I am running all the most recent versions of 
MythTV.  Any help would be most appreciated.

My xorg.conf and .nvidia-settings-rc files are listed below.  I am 
running FC5, 2111 kernel, and the 8756 nvidia driver.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:

# If you have a US Microsoft Natural keyboard, you can use:
#       Option  "XkbModel"      "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#       Option  "XkbLayout"     "de"
# or:
#       Option  "XkbLayout"     "de"
#       Option  "XkbVariant"    "nodeadkeys"

# If you'd like to switch the positions of your capslock and

# Or if you just want both to be control, use:
#       Option  "XkbOptions"    "ctrl:nocaps"
