SMplayer video stuttering when moving windows

[Vincent Tschanz]

Step to reproduce

1 Get the Elephants Dream movie at http://orange.blender.org/download (take the 480p h264/aac audio to ensure it can be played on a 5 years old system) Or another video your computer can play flawlessly.
2 play the movie in Smplayer, place the windows in a corner of the screen (or on your second screen if available)
3 open a nautilus window
4 you will notice frames drops in the movie during the opening of nautilus
7 if not, move the nautilus window, your movie will stutters

To continue the experiment :

- renice the Smplayer and mplayer process to -10
- set ionice of both to -c1
- go to step 3
