Summarized: - Within mediaportal playing videos stutters using the evr. Vmr9 renders vides without stutterings. - In GraphStudio, building the same graphs as mediaportal does, the video doesn't stutter with evr/vmr9. - As soon mediaportal is running in the background (of course without playing a video), playing the graphs within graphstudio also stutters.
