An advance welcome to Dallas!
Business Class provides a fairly decent selection of movies for their portable DVD players. I was thinking they offered about 25 movies, but just checked their website and found:
On select Boeing 767 flights in premium cabins, a personal Inflight Theater offers additional entertainment. The Inflight Theater includes a Bose® Acoustic Noise Cancelling® Headset, personal DVD player and a portfolio containing up to 20 DVD selections.
While it doesn't allow the flight tracking as on the 777, it's basically VOD since you do have the advantage of starting/stopping the movie as you choose, and not having to wait for the whole plane's entertainment system to recycle before you can start a movie. I've always been able to take a couple when they first come by, but then swap them out during the flight. And the Bose headsets make a huge difference in the entertainment, as well as the flight in general.
It might not compare with other carriers' newer in-flight entertainment systems, but it will certainly help the 11 hours pass reasonably well.
Enjoy the trip, and welcome to Big D.
