It's not that it judders on 24fps, far from it, very smooth, the panel 
performs better at 60fps when showing 24fps content (known issue on the 
panasonic plasma forums).

I can manually make the switch to run on 60fps, but my query is whether 
I can get the xorg to automatically send 24fps out as 60fps, to save me 
having to manually update everytime I swtich from 24fps to 50fps.


Cheers.
