Damn. I knew somebody must have posted these movies before. They're just too good not to have been. But I did a search and didn't find them, so...
Oh well. I got two more movies that weren't posted in that thread anyway.
Edit: And I don't care about spoiling the game for myself. I'm not going to be playing MGS3 any time soon anyway. Plus, I actually don't think the story in MGS and MGS2 is all that good, so I didn't really care what got spoiled for me in MGS3.
