Hi Mike,
I don't recall if your S10 pages tell the story, but do you know what happened with the S10 discs? The packaging says "digitally remastered" like all the others but none of them clearly were. Awful blurry mess they are, aside from the usual acceptable (barely) close-ups. My assumption is by S10 the sets weren't selling well, and CBS went cheap and decided to skimp, and the subsequent outcry (such as it was) made them backtrack for S11-12. Thanks.
