Jeremy,
what is your intention with that document?
If you want to show someone the movie with a bit of text for explanation, create a simple layouted document in Pages and export it as a HTML. Than compress it (with zip), so you can send it with e-mail or whatever you like. But hold the layout as simple as possible, because the HTML export of Pages is very basic.
Or export the Pages doument as a PDF (the movie schould be represented in it with the first frame as a picture) and put the movie beside in the same folder.
I think you have Keynote. If it is version 3 you can try to recreate your Pages document layout in Keynote and there you can insert the movie, too. Than export all as a QuickTime movie/slideshow. I don't know how good the QuickTime movie/slideshow export is with version 2. I have not the experience in Keynote to tell you more about that.
The only "professional" way to have a PDF with a runable movie inside is, to use an Adobe tool like Acrobat Professional or something similar. I don't know a program from other software developer that has the ability to do that.
Frank.
