I'm not sure I get the point of this. I could add Belgium and then basically list all spaghetti westerns ever made...
I assumed it was about announced DVDs that never got released. That's just because of the McGregor films though.
This is how I interpreted it as well.
OK, makes sense to interpret it that way but then it should be called "cancelled or postponed releases" instead of "unpublished titles"
Wouldn't it be more sensible to divide these by region codes or maybe by languages?
Well not for licensing questions, there it's more relevant which market we're talking about. A DVD distributor buys licenses for certain countries
There's also this topic:
And this one:
Should we merge these?
