Cannot make it play in realtime or windows media; cannot download quicktime ... but I saw the Chilean version and enjoyed it!
Are you using your work computer? Why can't you download QuickTime? It's worth the download. Better yet -- download iTunes, which includes QuickTime.
Note that the quality is better, and the filesize is smaller, with QuickTime. Why are most online movie trailers in QuickTime format? Because those who make a living making movies know QuickTime is a better format.
Just do it. :-)
