Limewire is just a way of sending files; it has absolutely nothing to do with playback issues.

You should download G-Spot, as someone here suggested. That will tell you what software you need. Here's the link for G-Spot:

Most likely you need Divx or Xvid. There's no reason not to download both. Here's a link for the Divx codec:

And here's a link for Xvid:

P.S.: Strictly speaking, there is no legal way to acquire movies on Limewire. However, when a film has not been released in your country, and there is no information on whether or not the film will ever be distributed, it's not unethical to check Limewire. Since the poster was asking about downloading a foreign film with subtitles, it's probably safe to assume he is within the moral right, if not the legal.
