Where can I find full episodes of Reno 911! or Mythbusters?

I want to watch them online, I've found that there is no legal site for watching full episodes so I'd like to hear about a reliable, less than legal site. Also, not so interested in short video clips. And if you don't know about those two shows in particular, that HBO miniseries about Marine Corps 1st Recon would also be welcomed. I'm bored, in college, and my TV is broken.
