I did a little math (uh-oh). A season of 22 episodes would comfortably fit on 4 BD-50’s and 1 BD-25. It would be possible to squeeze it on to just 4 BD-50’s. That would be 5 episodes per disc for 2 discs, and 6 episodes per disc for the other 2 discs.
I think that would be a lot better than the 11 episodes per BD-25 disc we get with the Chinese set.
