[MAC] Watching movies for free?

I need a website that lets me watch a movie for free. Actually, two movies. I want to watch Pirates of the Caribbean: Dead Man's Chest and Pirates of the Caribbean: At World's End. I've seen the first one, and the most recent one, but not these two. I was halfway through watching DMC with Graboid, however, I magically ran out of bandwidth, and it's hard to get more. I don't want a website that I have to give out a credit card or something like that for it. Nor do I want one that I have to, "Complete a special offer so we make sure you aren't a robot!" Or whatever. I just want a website where I can either download the MOVIE, not some stinking files that don't work, or where I can open it up and watch it straight from the website. And no, Youtube hasn't helped me on either of these videos. I have a MAC, once again, so please, something usable. No .mkv files if possible, because the Matroshka thing isn't working for me. I just want to watch a movie.
