Hi,
Not even DVD players can play all encrypted discs: because of region coding

The problem here is that your DVD drive is enforcing region encoding. This isn’t an OSMC issue. I believe that Matshita and some OEM DVD drives enforce this.
You should be able to set the drive to Region 2, which will do the trick. This can be done using a program called ‘regionset’.
Do you know how to use SSH?
Alternatively, you can change the region on your computer. But keep in mind that you can only change the DVD region a few times.
BTW: I have fixed the issue with some of your discs stuttering and it will be in for the next update.
Edit: I see this guy also had a similar issue and arrived to similar conclusions
