There are some issues with the Star Trek Fan Collective DVD releases in core.
Barcode 097360375145 - Star Trek Fan Collective: Borg
Shows only four episodes in the episode list.
Barcode 097360709742 - Star Trek Fan Collective: Klingon
Has no episodes listed in the episode list.
Barcode 097360709841 - Star Trek Fan Collective: Q
Core has the right cover, but has the wrong title and description (shows Borg instead of Q).
These are the only Fan Collective titles I have in my collection, but others were released, so I don’t know if the others have similar issues. You can see the full list of releases at the Memory Alpha Wiki.
