I have to preface this by saying that I do not use Blurays;

I do remember reading some articles going back a bit about issues with UHD disks only working if you met a silly list of requirements though, however I also seem to recall that MakeMKV added something which worked around that issue... Perhaps it is an option which needs to be enabled or some such?

Only really mention this in the hopes that someone who actually knows what they are talking about could elaborate (Or just tell me I am talking rubbish!).

How do you try to play blu-rays?

If you have a license for MakeMKV you can use the integration with VLC to play blu-rays. Is that what you're trying to do? Or something else?

Out of curiosity, why burn your rips to a DVD? Most people are trying to get the bits off a plastic disc so they can stop using plastic discs.
