I know they're taking the video screens off of the 737s. I haven't seen one in a couple of months now. Its all manual safety demos. The Airbi, 757 and 767 all have video systems. I imagine on a flight to the caribbean from PHL, they would have a movie, but you can never tell. In an effort to cut costs, they may have taken it away on all but Transcon and International (Overseas) flights.
If you're on a 737, definately no movie. Every other aircraft, its hard to tell. You might want to call Airways and ask, though.
