bit torrent. try sites like demonoid (u need an acc to download any torrents, but its a really great site if u can get an invite) or mininova or the pirate bay, fulldls, torrentspy, iso hunt, etc. (im not actually linking to any of them so i wont get in trouble, but goolge can be your best friend. if u still cant find them, i can send u them if u really need)
