Easy...
Step 1: get firefox
Step 2: get ad block plus with element hiding helper (I think it is made for mac, but am not totally sure)
Step 3: click on the block tab above the video, but do not block it, just copy the address that it is trying to block
Step 4: press cancel in ad block plus, and paste the link in a new tab (and press enter)
Step 5: go to file, save page as, then save the page. It will now open in quicktime as a .mov file.
I hope this is legal, but I am pretty sure it is, because I thought I saw a download link on the website anyway. If I find out it isn't legal, then I will make a point of it. Plus, it is totally free!
