All that's left to fix is getting the exact refresh rate on a secondary monitor. (Anyone?)
And where would I have to to this? I'm new to Linux =)

You said you used XBMC. I've never used it so I do not know how to change the settings on that. As for mplayer, the following magic spell does the trick for me:

mplayer -framedrop -autosync 2 -vo gl:yuv=4:lscale=1:cscale=1:force-pbo videofile
Better put those settings in ~/.mplayer/config so you don't need to give them explicitly every time.

Also, enable OpenGL sync to blank in nvidia-settings and use the __GL_SYNC_DISPLAY_DEVICE environment variable to define which monitor to sync on if you use more than one. I wonder why the syncing monitor can be chosen for xv but not gl in the gui.

It seems that no one answered the original question.

The modeline you created goes in the monitors section of xorg.conf. For example:

Section "Monitor"
# HorizSync source: xconfig, VertRefresh source: xconfig
Identifier "Monitor0"
VendorName "Unknown"
ModelName "SONY TV"
HorizSync 15.0 - 68.0
VertRefresh 23.0 - 61.0
Option "DPMS"
Modeline "1080p23" 74.176 1920 2558 2646 2750 1080 1084 1089 1125 -Hsync -Vsync

And the "metamode" would then be:
Option "metamodes" "1080p23 +0+0"

In nvidia-settings, you should be able to see the name of your mode: 1080p23 in my case.
Hope this helps.
