I'm also having the problem, that XBMC does not switch to 24Hz when needed (in 1080p).

After reading all hints here an the forum, i successfully managed to get XBMC to "think" it does 1080p@24Hz, but sadly it does not really do it (as my screen tells me, and i see the pulldown-judder).

After long searched I think that "RandR" has something to do with this. As it seems, this is the tool XBMC uses for the resolution changes. When I type "xrandr" in die command line, i'm just getting a

No screens found.

... message. I've looked around for a whole day, but I didn't find a solution for that :-(

UPDATE:

Alright, i've come one step further, xrandr works now after exporting the display using

export DISPLAY=:0.0

in the terminal...

Now I need a way to tell XBMC the same thing, because until now XBMC doesn't want to change the resolution at all :-(

UPDATE2:

After running the Export-command i get the following result von xrandr when running the menu:

Code:

Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      60.0*    24.0     50.0     30.0     25.0

This is correct. When starting a movie that is encoded in 1080@24p (having auto refresh-rate-handling activated), i'm getting:

Code:

Screen 0: minimum 320 x 175, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      60.0     24.0*    50.0     30.0     25.0

And nvidia-settings (as well as my TV itself) shows me:

Code:

nvidia-settings -nt -q RefreshRate
60.00 Hz

Looking in my /var/log/Xorg.0.log I also see:

Code:

(II) Jan 04 14:05:47 NVIDIA(0): Setting mode "1920x1080_24"

which tells me that setting the manual modeline should be working... but it isn't.

Somehow xrandr does not really effect the refresh rate, it just thinks it does. Does anyone have an idea how to fix xrandr? I actually think xrandr is talking about another screen than nvidia, but that did not help me so far in finding a solution.

I've alrey set a manual modeline that has been reported as valid, but this didn't change anything.

UPDATE3:

I think i'm gonna dump XBMC Live and install Ubuntu and XBMC on top of it. Maybe this way i'll get this to work (AND the remote)...
