This is being advertised as a 4 disc set instead of the usual 5 discs. So apparently CBS is not concerned with uniformity regarding their DVD sets. Instead of 5 discs with 6 episodes each, this time there will be 4 discs with 7 or 8 episodes each. I don't like it, CBS gets my vote as the worst studio for DVD's. Just look at what they've done to shows like My Three Sons and The Fugitive for example. The Gomer Pyle episodes are chopped up too with music segments cut from the episodes.
