Here in Canada, disc 4 of the 'Adventures of Superman: Season 1' set had the same content as disc 5. Via tvshowsondvd.com, I discovered an email address to contact Warner Brothers over this. This was the week the set came out, so October 17, give or take a day.

I've heard nothing at all since then, and two further emails to the customer service department of Warner Brothers have gone unanswered.

So basically, anybody get theirs or heard anything at all about replacement disks? There's no sense in returning the set where I bought it; apparently this defect was country-wide...
