Halo 4 - Theater - Hard Drive Not Detected

I am getting the following error when attempting to access videos in the theater:

> One or more players do not have an Xbox 360 Hard Drive. An Xbox 360 Hard Drive is required in order to watch a film.

I have a hard drive with over 100GB of free space; it is the storage device I am using when playing Halo 4.

Any assistance would be appreciated.

Xbox 360 Slim - dashboard version: 2.0.16203.0
Halo 4 Version: 1.03.00
