If you have a static IP (like me), then just let the video load about half way. Go to your browsers menu after it loads halfway then put it in "Offline Browsing" Mode.
Watch half of the video.
Then reload the page, click where you left off and let it load it again for the second half. Put that bitch in "offline" mode again, and play the movie.
This takes off your limit just the amount of minutes that it took your video to load only.
