OK - my TV (Sony Bravia KDL40W2000) is not 24hz capable. Currently XBMC is running all the time in 1920x1080@50hz, meaning I get the very nasty every 1-sec stutter when playing 24p (23.97fps) files (MKV's for example).

Can anyone help me with details of what I either need to be changing in my xorg.conf file, and/or selecting on the menu options from within XBMC in order to have access to 1920x1080@60hz, and also to have XBMC switch between 50hz or 60hz as required, depending on the file being played? (as I have some 25fps and 30fps files also).

Here is my xorg.conf file as it stands currently (system generated and unedited)
