What websites offer free streaming episodes of tv series (ex: one tree hill)?

No problem. Check out a little site called Hulu.com. It's a site that has episodes of a number of popular tv series that you can watch for free online. It also has a number of movies you can watch and channels you can connect to. I use Hulu a lot at my job. It's pretty cool stuff. Enjoy!:D

well, if you are looking for torrents, try www.torrentz.com..just type in what you want and it looks in most popular torrent sites and if its there, just click on it. the torrents who have been verified (honestly, i do not know what it means, probably it has good quality and no viruses and not a "fake" download) have a green check by the end of the titles. I checked one tree hill and its there..of course, the latest season (7 i think) is at the top because its the most recent. anyways, hope i helped because all i know of free streaming online are that of animes.
