I've been incredibly frustrated with this concerning the miniseries based on works by James A. Michener. The copyright there is owned by Swarthmore College (as I recently discovered) and (as I also recently discovered) they've been sitting on the rights for years apparently doing nothing with them. I can live without Space if I have to, but I'd been desperately wanting a copy of Centennial for ages, the VHS set was out of print and forbiddingly expensive used, I couldn't get in touch with anyone at Swarthmore to answer questions about the copyrights, and so I finally secured a set from elsewhere.

If it ever does come out in an official copy, I will buy it. But who knows when that might be?
