I have the same Problem with HD DVDs and I cant go back to an older version

[Woodstock]

There have been other reports of problems with HD DVDs since 1.17 came out. Possibly earlier versions.

https://makemkv.com/download/old/ is where you can find old versions of MakeMKV.

If you have a paid-for license you can use older versions of MakeMKV.
