The media might not last a long time but you can easily copy to new media at regular intervals. The movie loss issue would likely be due to no one copying to a newer media due to no one wanting to pay for that to happen. Though as someone else said is there anything recent worth keeping, most modern movies are political statements more than movies

I've had to do the same over the years. My stuff was on Commodore 5&1/4" floppies, then copied and converted to Amiga 3.5" floppies then PC 3.5" floppies then Microsoft word format then Libre/OpenOffice format.
I suffered losses along the way with stuff that I didn't find a way to convert at the time. Microsoft was especially bad at this, newer versions of their software would no support very old so if you skipped a couple versions you would suffer loss. Thats one of the reasons I learned to avoid Microsoft at all costs. The same issue as the movie example is going to affect businesses when they try to open their MS word 2003 document in MS Word 2023.
