No, vlc creates between 15% and 25% load, when using XVideo output without
scaling: (source are plain unencrypted vob files on the server).

Fullscreen mode (scaling) takes approx. 5% more.

You can see, enough idleness...

The question is, why amd_disconnect=true causes this distortion. I tend to
believe that dis-/reconnecting CPU takes simply too long in this scenario.
