As for DVDs/Blu Ray, I only buy things like Planet Earth or other docs. Sure enough, just yesterday I tried playing Planet Earth II on UHD 4K Blu Ray on an Xbox Series X, albeit I still have a 1080p TV (bought used) and 1080p Receiver (bought used, Sony STR-DN1000 that I paid $50 for) and it was glitching. sigh Time to hit up Bit Torrent and download a ripped version of the Documentary that I already paid for. Argh.
Both Blu Ray and Vinyl are susceptible to one day not being playable. By ripping them into digital, we can hopefully keep the content playable well into the future.
