How do I turn off Auto-Expouser on the D7000?

I have it set to:
ISO 100
Manual Expouser
Shutter 50/sec
Aperture f/4

I pan from inside my office and it is exposed properly, and pass an outside window, I expect the window to be blown-out, however, it adjust Expouser for the window?

I accidentally found the answer to this question.
For those that would like to know, you can turn off auto-exposer by going to:
The Shooting Menu
Movie Settings
and setting Manual Movie Settings to ON

From the Manual: Shutter speed and ISO sensitivity are adjusted AUTOMATICALLY unless ON is selected for Manual movie settings and the camera is in the "M" mode.

You'll want to look up the specs of the WDTV - and see what format it likes best and what the best CODEC is also gong to be most compatable.
