As funny as it seems, I am glad nobody thought about it as a true way to prevent cross-zoning like with ridiculous unhelpful initial DVD discs/players Zoning where you could only change your zone 5 times which btw wish someone sue player makers for that.

Its just a matter of reversing the tape content, but I could imagine zoning south versus north hemi, so Australia VHS would not work in Europe :) I mean it would work but you would watch in reverse :)
