[MPlayer-dev-eng] [PATCH] print DVD volume ID with -identify

[Reimar Döffinger]

Hello,
attached patch adds a ID_DVD_VOLUME_ID message, there was a question
about this on -users.
It might even make sense to print the information without -identify, but
that is trivial to add later.

Greetings,
Reimar Döffinger
