Hmmmm... interesting approach. Is the license "permission" to watch it from sony during the duration of their contract, or do I "own" the movie, but not how it's presented through Sony, in this case.
If it's the latter, copy/rip the media.
A short aside:
I have a fairly large audible account. I noticed about 10 years ago, I still have books in my queue, but I'm unable to download/listen to them. Audible explained the licence to me, told me that it should appear back in my "library" eventually but might take years (and maybe never), but here, have a free "credit" (which is basically, another free book).
Had that happen about 6 times over the last 10 years (the most recent was about a year ago. Each time, I got a credit -- and with the exception of the most recent, the book re-appeared in my library. If the pattern continues, I should have it back in my library within 2 years from when it was removed.
I can live with that.
