I just bought Series 7 and was pretty miffed when the final listed episode "Showtime" was replaced with the next episode "Potential", which, before I realised what had happened, told me exactly what had happened on the episode I missed. And it looked a good one.
It doesn't seem possible that this could have been a one off, what with the way these things are mass produced. Has anyone else had this problem? Do the distributers have a policy on this? Is the shop going to object to me seeking a refund as there's nothing technically wrong with the video?
