Problems With Jurassic Park 3

[SiCk Of ThE PaIn]

ok,im downloading jurassic park 3 (i checked it in various sites so its no fake) and when i try to open it with avi preview it says it doesnt find any video info(or something like that) but it DOES find audio,so...what could it be?some video codec or what?

Thanks

You're probably missing a video codec.
