I've recently installed Ubuntu 11.04 Natty on my eMachine / Revo along with Boxee. When ever playing back HD content though the playback is choppy. I've checked the OSD to find out info on video playback.
The fps fluctuates from 24fps to 18fps and both CPU1 and CPU2 are running at about 90%.
Any ideas why there's problems with video playback on Ubuntu 11.04—I've got no problems on another machine running Ubuntu 10.04 and fps stays at a constant 24fps and around 20-40% CPU usage.
Is this a specific problem to Ubuntu Natty 11.04?
