I just moved and don't have HBO/Showtime like I did at my parents house. I know its capable to watch streaming video through a PS3 but I didn't know what all it entails or any free site that I could watch shows on.

I use sidereel.com to watch entourage episodes on my PS3. Haven't really searched the site for other shows but they are usually posted within a day of the episode first airing.

Thanks! I always thought those sites that ask you to sign up were pay sites.

Nope, haven't had to pay anything. There might be a pop up ad once you click on the play button, but just close it and then you are good to go.
