I was going to post the code to embed a QuickTime movie in your web page, but apparently that is the old school way of doing it. The new hip way is to put a script tag where ever you want the movie to appear which calls a JavaScript (provided by Apple). The JavaScript will create the correct <object> and <embed> tags for you.
A complete example, along with the JavaScript can be found
here. Oh, and let me know if you want to see the regular old <embed> tag code for embedding it in your web page without using an inline script.
Note: you will need QuickTime Pro ($29) to convert the movie to Fast-Start. If you have QT Pro and need help exporting the movie as Fast-Start, let me know. If you don't have QT Pro, give me the link to your web page where your 51MB
behemoth movie is, and I will download it and covert it for you. I can even convert it to something like h.264, which will give great quality at a much smaller size.
Oh, and I would stay away from torrent files. P2P networks aren't designed for delivering media content on your website - they are for transferring and sharing large files (among other things, I would guess).
