I just want both versions on the same disc. Doesn't Blu-ray allow something like 40mbit/sec for the video? Aren't most movies encoded at an average of about half that? (if that's not possible they could have 2 discs in the case - 1 for each version).

Perhaps there's another way, like for this movie, say they filmed it with the whole 1.78:1 frame containing the image, but for the cinema release they decide to put black bars on as the director intends it to be put on cinema release at 2.35 or 2.39:1, but the whole 1.78:1 frame contains proper footage (no microphones/lights) - the answer might be to encode just the 1.78:1 version for Blu-ray but have the black bars on the Blu-ray be a graphics layer (if that's possible - using BD-J?) - so the 2.35:1 version on the Blu-ray disc would look exactly like it would if you had encoded it at 2.35:1 with the black bars encoded in the picture instead of as a graphics layer. And the 2.35:1/1.78:1 toggle button would just make the graphics layer visible/invisible?
