VLC should play the film. If not, go to the VLC menu File>Open & direct it to the movie.

As far as the nimo site goes, remember I said to ignore mirror 1 link & only click on the mirror 2 link (it's also been moved but should link up with a redirect link.) But if you're having probs with it, then try the other link I gave you. That brand of codecs is also very good. Here's another if you want (but I don't know how reliable these ones are): http://www.free-codecs.com/

There is of course always the possibility the movie it corrupt. If you have the full versions of Nero or Roxio Easy CD/DVD then try to play the movie with them. If they can't play it then it doesn't look good.
