This is something I've learned to live with over the years with xbmc. Currently the best I've come up with are these settings(which are the same I've used with ati 4550,5570,nvidia 7600,8600,gt220,gt440 on both intel and amd rigs)

adjust refresh to display
sync playback
sync method - resample audio

and set default delay of 125ms for 23-24fps material in advancedsettings.xml
It's not perfect, but 90% of the time never notice anything outside of +-25ms

Here is the advancedsettings used(from wiki) for anyone not familiar:

PHP Code:

<advancedsettings>
  <video>
    <latency>
      <refresh>
        <min>23</min>
        <max>24</max>
          <delay>125</delay>
      </refresh>
    </latency>
  </video>
</advancedsettings>
