Have you ever been able to make that adjustment before?  Just like when you are shooting stills, if the camera is in auto exposure mode, then I would not expect the camera to allow me to change any of the exposure settings, not just ISO.

I think Waddizzle has got a handle on this one. Had you previously been shooting video in Program mode and not had this problem? If not try using Program (P mode) and see how the camera responds. It will still give you fully automatic exposure but should allow you to make a few more settings,  adjustments and customizations than the AE mode setting.
