Yes, no VLC for OS 9.
Doesn't your DVD Player app work?
The OS 9 version of the DVD Player can be downloaded here - http://macintoshgarden.org/apps/apple-dvd-player
There's even a patched version of the DVD Player on that page, if you have a non-Apple DVD drive in your Mac.
Ah, I see you have one of the PB G3 with the decoder card for viewing DVDs.
Are you sure that your DVD drive is still working?
