That depends on some things.
You might be able to burn that movies to DVD in a format that's recognised by a standard DVD-player. That's a rather time-consuming thing. A free program to try is DVD Flick.
You might be able to use a laptop or desktop at work that can you can use to play that movie directly from the external drive. That's much easier. A second hand PC wouldn't be too expensive. And maybe there's already one available?
At home use any PC or laptop that has video output that matches with the video input of your TV. Using hdmi on both with a simple hdmi cable (a few meters) is the easily the easiest.

I wanted to download movies to a 3TB External Hard Drive so i can bring it to work on night shifts and hook it up to the 50' Plasma moniters there. I currently have a DVD player and computer speakers that i use. My question is what is the simplest, least expensive way to playback the movies there at work and also will it work easily for me with my TV at home?
