Sorry MrMidnite but what are you actually doing on a forum like this if you don't understand the absolute basics?
I presume you're on a windows machine!?
Quicktime player is free!
You can change the wrapper (.mov) to .mp4 or .avi and it will play back in Windows Media Player (albeit with a gamma shift).
There are countless players out there that are free and more than capable of playing back the movies you record on your T3i.
If you want to transcode you can use GoPro's Cineform Studio FREE. That will give you Cineform 10bit AVI or MOV files. Google it.
I suggest you jump on Youtube and familiarise yourself with the basics of your camera before getting into anything Magic Lantern related.
