|My Roku HD|
I also, though, have a USB TV tuner for my computer, which I use with Windows Media Center to record TV shows or movies. After it is recorded I use MCEBuddy to compress the video (which is usually a couple GB) and remove the commercials. MCEBuddy runs in the background and works automatically after the initial setup. Needless to say I have a decent collection of movies and TV shows in video file format.
This lead me to search for a solution to use my Roku to watch the videos I recorded earlier. Since my tube TV does not have any HDMI connections, I can't plug my laptop directly into it. Plus, that isn't the most convenient.

The other feature with Plex that I love, is the ability to "Publish" your server to the internet for access via Plex's website or one of their mobile/tablet apps. I can watch my content anywhere with an internet connection, just as long as my server, router, and home network are all online and functioning properly.
