Enjoying the sets so far, I now have seasons 1-4, and have 5 and 6 pre-ordered, but I've just been sitting here wondering, since MPI Video is using later "rebroadcasts" for some episodes in the earlier season releases of "The Adventures of Ozzie and Harriet" to make up for lost/severely damaged...
Mine arrived in the mail today, both cases have chips broken out of them. However, the discs themselves look fine, so I don't think I'll bother trying to return them.
