Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I feel this is kind of a dumb question but I can't find a solution that's working for me:

every now and then I have the need to rip copy protected dvds. In the past I have used Handbrake with libdvdcss. But now there only seems to be flatpak versions of Handbrake for linux and these versions can't access the libdvdcss library.

VLC should be able to do the job but for a specific dvd I wnt to rip now, I produces out-of-sync video/audio tracks and I haven't been able to succeed.

I can't believe ripping dvd's can be that hard. Do I miss something obvious? Any tips are appreciated, aside from just download it - I can't find the respective media anywhere...
