I've been having some small sync issues with 24p content as well (about 50ms delay needed). I recently added uNiversal's modelines to my xorg.conf and it seems to have fixed the issue (at least made it much less noticable). So, the only thing that I've changed is that the 23.976 mode is being used instead of the 24.000. I have Sync playback to display disabled.
