I boot back to the MS dashboard and use the built in video player (it reads my external as a portable device, and contains all my media).
The question was how does he play the videos off his internal hard drive, not how do you play videos on your xbox 360.
You can try this
but IMO seems like more hassle than it's worth. If you still have an original Xbox I'd use that instead because the only other way is to get an app called FFplay. It's fairly new and still glitchy.
