Forum:Where did these DVDs come from?

As any British Trekkie who frequents their local cash converters should know, it's quite common to come across individual Star Trek: TNG DVDs, in normal-sized DVD boxes (not slimline ones), each box containing one disc which contains three episodes. An example image is here (sorry for the low resolution - it's the first one I found on the internets): link. Did these come from a box set? Or were they originally sold separately? Is there any particular reason why they aren't on Star_Trek: The Next Generation (DVD)? Muzer 18:42, April 19, 2011 (UTC)
 * These DVDs came from Star Trek: The Collector's Edition --Jörg 18:50, April 19, 2011 (UTC)
 * Ah! That makes a lot of sense - yes, I've seen the TOS ones too... and the film ones for that matter (I have quite a few of those). That also explains why they have the spines that make up a picture... thanks a lot! I may try to explain this to Cex, as they're trying to sell a single one of these for £15, whereas cash converters sell them for £0.7-£2... Muzer 19:04, April 19, 2011 (UTC)
