This shouldn't happen anymore after
commit d42e8f558ef0b6efa36db8bebf1ee6237da2b024 and after wiping

You should have the dvdreadsrc element form gst-plugins-ugly installed.
Then it _might_ work, but many clients seem to have an issue with not
being able to do random access on the URI.

Good hint though, I should possibly check for dvdreadsrc's
availability.

Btw, it's not chapters, it's individual titles that you access.
