When my nvidia clocks were full speed I had those same symptoms.
However, it looks like your gpu and memory clocks are slowed down, 196
and 499 respectively. I run mine at 200 and 756. I use the following
to set all my nvidia related stuff.
These lines in /etc/modprobe.d/options.conf
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
options nvidia NVreg_Mobile=0
These lines in /home/$user/.mythtv/session
#!/bin/sh
xset -dpms
xset s off
nvidia-settings -a GPUOverclockingState=1
nvidia-settings -a GPU2DClockFreqs=200,760
This line in the Device section of /etc/X11/xorg.conf
Option "RegistryDwords" "RMDisableRenderToSysmem=1"
These lines in the Screen section of /etc/X11/xorg.conf
Option "UseEvents" "1"
Option "NoLogo" "True"
Option "Coolbits" "1"
And this line in the Extensions section of /etc/X11/xorg.conf
Option "Composite" "Disable"
And running this to enable nvidia Xvmc
sed -i -e 's/^libXvMC.so.1$/libXvMCNVIDIA_dynamic.so.1/' /etc/X11/
XvMCConfig
I think that's all of my video related configuration items I use for
running Mythbuntu 9.04 with MythTV 21.
I hope that helps, but this could be a 22 issue. I have not tested
myth 22 frontends yet with the ATV(I'd mostly be worried about memory
usage with 22 and Mythbuntu 9.10). Although that is high up on my
priority list as there are some 22 backend features I'm looking to
implement in my setup.
