Net Transport can grab the movie from the url that UrlSnooper found for you
As you say, the clip starts with a "trailer" of sorts, but Net Transport finds the secondary download. Be warned its 44mb big, but a quick test shows that it does download and plays fine.
I've mentioned Net Transport twice today -- i'm not a paid spokesperson but i do like the program. There may be freeware tools that can do it too.
By the way i just noticed that our discount on net transport is still available for supporting members:
