Yo if you aren't torrenting you are missing out massively.
Get and run this firewall to protect yourself from the MPAA's snoops:
http://www.peerblock.com/releases
Then get this free tiny torrent client:
http://www.utorrent.com/
Then go here and search for movies you want:
http://kickass.to/
or here:
http://bitsnoop.com/
Pick files with a lot of seeds and not too many leeches.
Have fun. Be careful, you will fill up your hard drives and become addicted to buying more drives to compensate. (650 gigs in movies and 440 gigs in seasons of tv shows right now...)
