I recently got season one on DVD, and I love it. I'm concerned by episode 30 though. It does'nt seem to be in order with the other shows. In this episode, Donna Reed's hair is much shorter and appears to be lighter. Plus; in the opening credits, bubble lettering is used when the actors names appear on screen. In the episodes following, the names are back to the original font except for one other episode. Just wondering why. Can anyone answer my questions?
