Have you watched movies on your computer before? If not, try it in your DVD drive and run it something OTHER than MS MediaPlayer. It MIGHT work, no promises- I've never tried PAL format, but if your DVD drive is still trying to figure out what zone it lives in it might work. You'll probably have to get codecs for it, but that isn't a big deal.

Odds improve if it is an older model drive in a Linux machine; go down if you are running a Mac or Vista.
