I'm running my f/e on a m10k and I find it best when using Via XvMC 
mode. I've applied all the sugguestions on the XvMC wiki page so that 
may be a place to start.

I'm using Chroma Key OSD.

The biggest source of stuttering I found was when I was streaming from 
myth b/e rather than getting the data via a shared NFS mount. Shared NFS 
Mount is 100x better (an approximate measurement!).

When I go to sleep/wake up my EPIA it sometimes seems to jump to 
stuttering mode. A proper reboot fixes this although I believe this is 
due to stale NFS handles and thus myth resorts to streaming. The reboot 
just clears them out. Not really looked into it in any great depth yet.

Hope that helps.
