>Description:
(First I want to state that making private copies of DVD media is legal in the country I live in.)
It appears like it is currently not possible to use dvdbackup on NetBSD/i386. Or at least on my specific hardware.
Running dvdbackup -i /dev/cd0 -M -p leads to the following output:
bash-5.2# dvdbackup -i /dev/cd0 -M -p                                                                                                        
The IFO file ./Batman Robin/VIDEO_TS/VIDEO_TS.IFO exists; will try to overwrite it.              
The BUP file ./Batman Robin/VIDEO_TS/VIDEO_TS.BUP exists; will try to overwrite it.

I installed dvdbackup via pkgin, then installed libdvdcss via pkgsrc. Running dvdbackup at this point already produced the crash. The command I ran was "dvdbackup -i /dev/cd0 -M -p". However, "dvdbackup -i /dev/cd0 -I" works fine.

Then I compiled dvdbackup from pkgsrc and tried this version. No change.
