That's right, so the transfer with the least benefit from putting it on DL instead of SL will be X0 But I really wonder if you'd get more compression artifacts in an anamorpic transfer than in a non-anamorphic one... There is less black and more image, this makes it harder to compress. But it's also less sharp (when watching them both in a 4:3 ratio) which makes it easier to compress. Would that cancel each other out?
