----Can please report what is using the cpu (i.e. watch top) whilst playing back a video?---- VLC is at the top, Compiz below, and xprop third.
----Then follow that up with the highlights from 'sudo perf top --sort=dso' and 'sudo perf top' (apt-get install linux-tools). Just cut and paste the first few lines of where the time is spent at a random point of time during playback.---- This is going to sound really stupid, but I don't know how to copy while this runs; I tried right clicking and I've tried shift+ctrl+c with no luck. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1103236 Title: Choppy and pixelated video on Macbook Air 5,1.
