Best Way to Watch MLB.TV?

What is the best way to get my MLB.TV account to play on my Apple TV 2?

So far - on your computer.  That is until someone makes an XBMC or Plex plugin (but I would avoid Plex, because you need a powerful computer running which streams the video/audio to the ATV2).

Someone please correct me if I'm wrong.

yoy can set up PLAYON in your network on another computer.  and watch the UPNP streams. 

Would the 1st generation of unibody macbook pro (circa 2008) be conisdered a powerful enough computer for Plex, if they made a plugin?
