....thanks for the tip, but that definitely doesn't measure the refresh rate. it's rounded to the nearest integer.
I will look in the logs to see if it specifies it before rounding.

quick question in regards to refresh rate ...
I currently have "adjust display refresh rate to match video" check and able to get my tv to change to 24hz when playing a movie. I was curious as to what effect "sync playback to display" has. is it necessary to have that check also?

What that feature does is described here: http://forum.xbmc.org/showthread.php?p=336538

I can't get sound during playback...but system sounds are okay. Any ideas as to where I went wrong? I did update the Nvidia drivers just prior to installing this script. Other than that....Buttery Smooth! My Avatar Backup had major stutter where Jake first meets the Queen. Now ... Smooth!
But, can someone give me some clue as to why the audio doesn't work?
Edit: Don't know why but it took about 3 reboots and a rest period of 1 hour for the sound to work again. Oh, well.

Any idea why my HD DVD backups are all nothing but Stutter after the script?

Since the guide doesn't really work for me (still having problems with playing videos with different refresh rates, I finally decided to use XBMC Live just for playing 23.976Hz files. But I can only choose 24Hz playback at XBMC.
Can someone tell me how to add 23.976Hz to the playback menue?
I have to add that I am totally new to Linux. So I need "help for dummies". :-)

Script worked for me, thanks. I still have a couple of things to fix before it's perfect though...
1. Still loosing the edges of the Ubuntu desktop because of scan issues. Not that big of a deal as the purpose of this box is to run xbmc; would be nice to fix though.
2. The receiver and screen have to be powered on before the pc. If I boot the pc first it comes up in low graphics mode.

There's no way to add that, randr rounds it to 24 hertz, however when you choose that it will actually be 23.976.
