after some work I finally compiled my own XBMC and VAAPI works fine at 1080p@50Hz.
(lates xbmc from git, latest libva, latest fglrx 11.10)
I want to watch movies with 24Hz, but as soon as I activate it, i got a lot of Tearing and lagging Videos.
While watching a HD movie and browsing through the xbmc menus, the video is lagging too. (at 50Hz)
Could anyone help me to get 24Hz working?

Just lock it at 60Hz and tell xbmc to resample audio. No headaches at all that way. This whole 24Hz thing really is much ado about nothing.

Done the Composite thing and it didn't change a thing.
Is this related to the fact I'm running command line Ubuntu minimal install?
Also bumped RAM for IGFX to 1GB which is the max on my Gigabyte E350N-USB3 for some reason. Nothing was changed here too.
For the compiling thing, I reset git and ran ./bootstrap again just to fail here

It looks like you're missing dependencies there somewhere. Did you install them manually from the README.linux or did you use apt-get build-dep xbmc after adding the unstable ppa?

What WytRaven said, Also if you have a desktop environment installed you can enable the tear free option in amdcccle. Perhaps somebody could give us a command to enable this feature via command line.
Ah bless arch wiki, ask and it provides. Even though I don't use the distro I love their documentation.

Restart X or reboot after the toggle.

@WytRaven 24Hz ist not about headaches! with 24hz there is no framskip like with pal(50hz)/ntsc(60hz)
Just watch a movie on a good HDTV and switch between 24hz and 50/60hz... you dont wanna look a movie without 24hz anymore...
thanks, but it isnt working.
With TearFreeDesktop enabled and 24Hz my video is stuttering really hard.
i tried to record it: https://www.dropbox.com/s/z3dal86ft05qh1i/video-2011-11-07-17-56-42.mp4
Any hints? (CPU is at 15%, vaapi works)

No, i did only what is on the OP.
Should I run this apt-get build-dep xbmc command?

I did run apt-get build-dep xbmc and now I'm on the horse.
IMHO, this should be added to the OP too.
Now lets see if this fixes the crazy FPS thing.
Edit: It didn't help with the crazy FPS.
Got to be something with Linux detection of my TV.

there are some rather deep problems with ati vaapi and 24p in XBMC. Without the patches from FernetMenta(read ~15 pages back) you will never get it working smoothly. Even with the patches the problems are not really fixed, but only less noticeable.
I for one, am waiting for direct xvba support, which is currently in the works.
- dermute - 2011-11-08 11:22
Oh thanks... I searched for that problem you discribed and it seems to be serious and I am not the only one...
lets hope they can fix it soon (Fermet said, fix is not expected for Eden )
- wsnipex - 2011-11-08 12:12
I don't care about Eden stable, since I compile from GIT.
If it does not get enabled in the official nightlies(as it is with vaapi), I bet someone will provide a ppa.

Starting at the beginning of the thread is usually the best point, then use all relevant references near the end of the thread since these typically will pertain to current issues. If you are having trouble understanding installing minimal Ubuntu I suggest you install Oracle Virtual Box in your desktop pc and play around installing minimal Ubuntu in virtual machines first. Once you're confident with your minimal Ubuntu installation use it on the real system and move onto installing xbmc. This will save you a lot of headaches.

Removed potentially confusing/damaging information. I don't want ppl chasing their tails or blowing up their displays/systems.
Good news I think I almost have 24fps working.

looks like hes making progress
