I'm using ubuntu 13.10 and have problems getting xbmc to play nice with video playback.
Using window mode playback is fine, but in fullscreen mode I have massive tearing and slow playback (both 12.2 and GIT), I've spent the better part of the day trying to figure out how to get smooth perfect playback, but no success.
Finally I found the option "TearFree" to add in xorg and finally the tearing is gone. However, playback is not smooth, it cannot sustain the framerate it's supposed to. 50hz video is playing at 38-45 fps.
lower hz content is playing at the right fps, but still it's not perfect. And I notice the missed counter going crazy.
Any suggestions ?
EDIT: Cpu usage is at all times low on all 8 cores.

Thanks for your suggestion!
Unfortunatly there is no build for ubuntu 13.10 vaapi-vpp
If I disable compositing will unity work ?

I ran xbmc standalone on a seperate X session and got perfect playback. I guess I will look into running a seperate X session on each monitor output on my gfx card, it would be the perfect solution I think - hope it's possible.

In xubuntu you just have to choose settings -> windows manager tweaks -> compositor tab then deselect enable display compositing. Please try fernet mentas builds on Gotham not frodo. sudo apt-add-repository ppa:wsnipex/xbmc-fernetmenta-master
You still need vaapi drivers for Intel. They are way better. Buffering, vaapi... Glad you got it sorted. Ubuntu compositing was the reason for my switch to xubuntu. I tried mainline frodo and it was no where as good as fernertmentas branches. For audio try analog sound first. You need new kernels for HD HDMI goodness.

Theres a lot to be said for sticking to 12.04 LTS for an XBMC machine.

What to you mean by support multi monitor ?
I was using the Team XBMC Nighly PPA, in your sig
ppa:wsnipex/xbmc-fernetmenta-master is different ?

Thanks for more suggestions guys, I'm stoked. The build from fernetmenta-master ppa is freaking awsome !!
I've tried 24p, 50i and 50p - all worked perfect, xbmc in fullscreen on one output and deskop on another, seamless using mouse and keyboard on both. This is just what I've been looking for.

I just like to update here, I had done so much testing - different settings, tweaks and config files, and I rather liked Xubuntu over normal Ubuntu so I did a fresh install of Xubuntu to get rid of all my previous efforts and get a clean install.
I then continued to install compton to get tear free composition in Xubuntu.
And the important part, I still have perfect tearfree and smooth playback
no tweaks, no xorg settings, no special drivers, no disable compositing. Just this special XBMC build.
