poofy,
I gave that a shot but just recently upgraded to Eden on Ubuntu 12.04 and when trying to follow the instructions after loading in the new Xorg file and restarting lightdm (not gdm as I found out), my system hangs at a black screen and will not boot. I don't believe this guide is current for builds on 12.04.
When trying to match refresh rate to content now, I show 55hz to a 24fps film giving obvious jutter. I know my television is capable of displaying 24hz and my content is 24fps so the only missing link is getting my Nvidia 8400 to output the appropriate refresh. Am I outta luck?
Thanks,
Rob

I will be honest I have only tried that on XBMCbuntu which is 11.10, but it works perfectly there and every previous release. Xorg hasn't changed in years so unless something new is messing it up (like wayland) then it should work.
Try the script. You have to edit it first (change the four instances of XBMClive to lightdm as you discovered). I would love to know if that fails.
It can't be the card. It is some EDID nonsense.

Interestingly enough, I WAS able to get this to run and now my codec info reports 24hz with content at 23.97fps. Only problem is, the judder is now worse than it was at 60 hz. Any idea what I may have done wrong?

I have a hard time believing that the countless people who are striving for perfectly synched 24fps playback are doing so to watch what I'm watching...
I have another xbmc eden build on a revo 1600 that had multiple refresh rates out of the box and switched the display with ease. It has buttery smooth playback. I'm not sure if I'm buying it poofy.
The big difference I'm seeing between the two builds is that my Revo will switch my LCD TV to 24 hz while this current build leaves it in 60 while displaying 24 in the codec info. Thoughts?

Well definitely don't buy it if you have another box that performs differently. 24p is 24p- it should work the same on all clients. I just posted that link because more than once on the forum someone has gotten 24p to work only to discover the flaws of using it. What you have is beyond that apparently.
The TV is what tells the truth. It sounds like the TV is staying at 60 hz but the box is changing to 24p, which would explain the terrible judder- nothing is correctly doing 3:2 pulldown. It must be rough.
What that tells me is that the TV is still having trouble identifying that the content is being sent at 24p. But the system thinks that is what is happening or it wouldn't play in 24p.
I have gone too long without asking- what model is the TV? Maybe I can hunt down a custom Xorg for you.

Sorry for the delay.
Looking at the log the TV rejected the modes you had. I would nuke your Xorg.conf and run the script again.

As in simply run it again or restore it to the original xorg file that I have backed up then run the script again?

Restore the original and run it again. Good question.

Thanks for that log. From the looks of it I would swear you have an audio problem. But the way your TV is acting and the fact that file is a non-standard resolution (800h) and the 8400 gs is a Feature Set B decoder makes me also wonder if that is an issue.
Will you try something else? Will you find a file in your collection that is completely standard (so height exactly 1080 or 720) and play it and shoot over the log. Also how is your audio configured?
