Try a reload of the official Apple firmware and see if the video plays properly. Then redo your JB and see if it corrects itself. It does happen that a JB may be crappy and need to be redone. It's not often but I'm sure it does happen from time to time. It could also be one of your apps or tweaks can you remember what you installed right before this started to happen?
