My copy of Punky Brewster Season 1 Disc 1 seems to be missing the end of Glomer's Story, the bonus cartoon on disc 1. Is this mistake universal or is my DVD solely flawed and should I return it? If it is universal I shall keep it but I need to know if it is a unique case where in I need to return and exchange as soon as possible. If you have it, can you check? Thanks in advance.
