I have to investigate this further. I bought a bunch of bluray UHD documentaries that I cant watch because my 4K TV is a 'monitor'. Which I only found out was a problem after also having to buy some expensive 4K HDMI cable which was supposed to fix the problem.

Since I couldn't work out how to backup the discs, I now also just buy 2nd hand DVDs for when I need my pacifier box. Anyway, for this old man it turns out that the old movies are the best; no shaky camera and clear audible dialog. Plus some of the modern discs are now also polluted with adverts, horrible.

If we lived in a sensible world, buying the item once should give me rights to every format available. I might even consider digital purchases again if that was the case, especially since we have seen too many of these services fold and take our purchases with them.
