Could you please stop filing bugs for versions that are not in Debian? It
happened in the past that bugs filed for versions of packages from
deb-multimedia were not present in the official Debian packages.

The "dvd-image" option doesn't exist, did you mean --dvd-device?

I can't reproduce.

Would it be possible for you to upload this dvd image somewhere so I can test
this? Or even an image with only the affected track, if it still causes the bug.

It would be also useful if you could provide a backtrace of the crash (using
gdb) with the mpv-dbg package installed.

Cheers
