You can use TVersity or Winbdows Media Player 11, WMP11 will mostly likely already be installed on your PC if you have vista, all you have to do is setup sharing options on your pc then search for the media server on your ps3. You can also search myps3 for threads already on this topic.
TVersity is a very simple media server & I would recommend it if you have any issues with WMP11.
