DirecTV on Continental Airlines - NO captions!?

I was pleasantly surprised to find that Continental Airlines has LCD screens in all seat backs this last week. Wow, how this will make my 6-hour flights pass by more quickly. EPIC FAIL!

There is no way to enable CC on their systems. Isn't there some law against this? Seriously unbelievable that in 2011 we can stream whole movies on computers smaller than our hands and we still somehow lack to "technology" to accommodate Deaf and HoH needs to captioned video.

Thanks for nothing, Continental.
