But why does it work on both cores in Windows (I'm using VLC in WinXP)
and the cores are loaded like this: #1: 65-70% #2: 55-60%.
It seems that H.264 decoding itself is not able to saturate a single core,
as long as other tasks are all running on the other core.
So what's different in Fedora that everything runs only on a single core?
Thanks, Petr
