Kindda a newbie/non computer guy here who's figued it out. Here's how I do it.
First. Download Vuze. (
http://www.vuze.com/download/ )
Then, I use BtJunkie. (

Use the search function, click on what you want to download and scroll through the comments section. Usually, you will not get a good DVD rip copy until the movie is out on DVD (obviously, lol).
Then click on 'Download torrent'. Vuze will do the rest.
I copy the file to an external hard drive that plugs into a Western Digital gadget that is hooked into my home theater receiver via a HDMI plug. Works perfectly thus far.
Good luck.
