B&W G3 DVD player won't work

Hi all,
This is my 1st post and I'm new to macs. I have a B&W G3 350 with OS 9.2 installed. The problem is I have installed a Lite-on DVD ROM drive, which is recognized and works. I have booted from it without problems. I just cant play DVD's! I have searched the net for a solution and have even tried...

But the DVD player program wont open.

Any help would be greatly appreciated!

It reads data DVD's, but won't play videos?

I would think you'd need an mpg2 decoder.

Nah, its all good. Fixed it and it works!

Glad, you found a resolution to your problem. What did you do to resolve the problem? Some one else may come along, with a similar question.

Basically, I had a bunch of ATI drivers that were in a folder called "Extensions-disabled", I just put them in the extensions folder and re-booted and it worked. I bought this mac used and I'm pretty much a PC guy.
