Alright, I have no idea how the download world works, so maybe somebody can explain it to me in laymans terms?

Let's say I want to download episode one of season six of Entourage; I download a torrent of that description, now what do I do/download to watch it as a video file?

Can anyone help me? I know this is a noob question, and I'm sure that there's a thread for thsi, but I can't be hassled looking for it...

Thanks alot!
