The cache value is set back to default because 65536 is out of range. It's limited to 65535, actually.

Now, about the HD video, i was trying to make a joke about badly synch'ed lipdubbing during her concerts).

I'll try this video again when youtube gives me more than 15kB/s. It's a bit painful to play a video at that speed.

[EDIT]: Ok, i tried. This video isn't even synchronous in 360p (where CPU is obviously not an issue), so it's either a poorly encoded video or a bug in mplayer decoder/sync code.
In 720p (with skiploopfilter=all), the CPU usage doesn't reach 100% continuously either.
