If you don't have a DVD codec installed, clicking on the link will not work. But you only find out after you download the 30 megabyte file. At least I think that's what happened.

But instead just go to http://www.panasonic.co.jp/olympic/ and you can watch these as streaming video. They are smaller that way, but you don't have to wait. And there are 15 films to choose from - the 5 commercials and 10 other short films.
