DVD menu blank, cursor is there

Hi. I have a lot of my DVD’s ripped to ISO, and put them on my NAS which is mounted through SMB. Most of them are series, in this example I use That 70’s show Season 2 disc 3. What happens is that the initial trailer / promo runs fine. When that ends it goes to the menu. The screen then stays blank, but the cursor / selector is there. The music plays. If I just enter the dvd starts playing. If I then go back to menu it works fine.
When I restart the DVD and am on the blank menu, when I just let it there, I guess at the point the music restarts everything practically locks up. 100% CPU load on all 4 cores and even SSH takes about a minute for each command to recognise, let alone reproduce it.

I came from LibreElec 9.0.2, where the menu’s work fine but there I have MP2 audio issues, which work fine under CoreElec. I have tried some development builds from LibreElec on kernel 5.x, which also have that DVD menu issue.
It’s similar to https://forum.kodi.tv/showthread.php?tid=335979 and https://forum.libreelec.tv/thread/9105-dvd-title-menus-rarely-appear/, and there are more to be found.

As this is my first post, it seems I cannot upload any files. I’ve put them on a onedrive.

The CoreElec log, so the one that is NOT working properly:

During the trailer I press UP to skip to the menu. The following line indicates that:

2019-11-01 16:04:25.083 T:4093931536 DEBUG: HandleKey: up (0xf080) pressed, action is ChapterOrBigStepForward

So from there on, the menu should be build up or shown.

For reference, I also have the LibreElec log, which does not have that issue. Not sure if that helps.

Same, I pressed up and from here the menu starts:

2019-11-01 15:38:58.093 T:4087463952 DEBUG: HandleKey: up (0xf080) pressed, action is ChapterOrBigStepForward

If there is anything else you’d want me to test or provide just ask. The wife and kids are extremely annoyed by this, which I understand. Would it help to try a physical DVD with an USB dvd drive for example?

Uch, these limitations for new users… I saw I put a wrong link in my startpost for the CoreElec log. However, I can’t change it as it tells me ‘new users can only put 2 links in a post’. I can’t edit the post at all as it keeps giving me that message.

So here’s the correct one:
