Use Different Player for XBMC

When playing files with XBMC, there is a slight “jitter”, when the motion is occuring on the screen. It is still very watchable but it is noticeable. When using Sapphire there is absolutely no jitter and plays perfectly. Is there a way to point the default player to use the player sapphire does ?? I have tried to work it out myself but I don’t know where the player is located. If you need more information let me know. thanks

In the settings for XBMC go into Settting->System->Video Output and set vsync to always. This will stop the jitter.
