I started watching these yesterday, and I think you’ve done a great job in terms of audio here, the transitions are seamless. However, I found the constant switch between 16:9 and 4:3 a bit jarring. Have you considered cutting the BR footage to 4:3 so the switch between BR and DVD footage is less noticeable?
I wouldn’t want that. Besides, from my understanding, the 16:9 are cropped 4:3 anyways, so it still would be rather noticeable
