Many file download managers allow you to run a command after your download finishes. Is there a command line to run a Windows Media Player 12 library refresh? Videos don't show up in the available list on my PS3 until the library is refreshed.

Right now, I manually open Windows Media Player after the downloads finish, watch the bottom-right corner for the refresh to complete (ie. Update Complete), then close the player. This works, but there has to be a better way.

Yes, I know PS3 Media Server would do the trick, and I do use it when I need to transcode something, but WMP is running all the time, so I'd like to take advantage of it.
