I did notice this. However, I don't watch any other content in Mythtv apart from TV. I use XBMC for this, and it also supports changing refresh rate.

I should have mentioned, I'm using the 185.18.04 driver. So you're saying disabling composite shouldn't be required with this driver? I definately had to do it, as I got some tearing otherwise. Strange.

Hmmm.... I wasn't aware of this, but that would explain my other post earlier today about high CPU usage. Do you know of the reason for this? Do you have a link with an explanation, or any workaround? When I use VDPAU, I get "micro pauses" ever few minutes, which effectively stops me from using it. If I went back to an earlier driver version (180.51?) would this stop? When I switch back to the Xv renderer, every now and again the CPU on Mythfrontend climbs to 80%-100%. It happens on some process in the X11R6 folder. Fortunately, as I have a quad core CPU, I'm not noticing any stuttering in video playback.
 
I'm using your repository to get the VDPAU backport. However, I was hoping to install the older nVidia driver I can see when browsing your repository. However, in my Synaptic Manager, I can't see the drivers listed. Do you know why? Any thoughts on how I can install these older drivers?
 
Many thanks
Aaron
