Hi Christoph ! For the stuttering problem it is cause by lack of shader horse power to use HQ upsacling AND deinterlacing together. Please try to set the upscaler from auto to "bilinear" or even "nearest" at the worst case. Also if you are using xbmc in a composited environment please turn off all compositing or even try to run xbmc in a separate Xsession. If that does not help, you probably will never have it working stutter-free with Clarkdale.
