Spice3d : Can you make a simple test? Run the same file on the default media player and try to see if the cpu goes higher? Why : if this is happening is because the cpu is jumping, then if playing (media engine) is consuming cpu there's no cpu for Canola to animate screens.

Mp3s are by far the best optimized on the device (IMHO) and this is why it doesn't make the canola choppy : /

Let me know how the same files are playing on the regular media player.
