John,
Powerbooks of that vintage won't mirror DVD playback. The video card and MPEG-2 decoder is physically unable to do so. To display DVDs on an external screen, you need to drag the menubar over onto the external screen to set that as the main screen and then launch the DVD player program.

If you try to set mirroring on while the DVD player app is running it will usually cause the app to unexpectedly quit and could have corrupted things. You may need to do a system re-install since it sounds like you've tried most other things.

One of the 5 Powerbooks I've had over the years was a Lombard Bronze keyboard 400MHz G3 PowerBook and I've been there done that.

Can someone out there help me

I have a G3 powerbook 400Mhz which I use power point on for work. The G3
via the ext monitor port drives a data projector. I was ask whether it
would project DVD's, which it had but when I tried with a Hitachi
projector it wouldn't. No probs must be something with the Hitachi
project. But now I cant superimpose the LCD screen on the projector
screen in the monitor options. Its either left right top bottom but not
over like the options say.

have I screwed up or is it a software, preference problem
