PowerBook G4 - DVD Burner not working..

Hi All! I am new to this...

I just spent HOURS creating a DVd on iDVD, and when I put a blank DVD in, nothing happens - I went to my settings and it says "When inserting a blank DVD go to : iDVD"- so I know my system burns DVDs... Does anyone know what I can do? When I am in iDVD, the "Burn" button does not let me push it, almost as if it's not allowing me or something.

If anyone has any advice please let me know. I just spent hours on this and now I can't burn it. Should I be looking at other settings?

My Mac :

MATSHITA CD-RW CW-8123:

Firmware Revision: CA14
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
Burn Underrun Protection CD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw
Media: No

Looks like you probably have a combo drive, which reads and writes CD's but is read only for DVD's. You should be able burn a DVD quality video onto a CD with your iDVD software as long as it's short enough to fit in that format. However, you'll either need to upgrade that drive to a superdrive (aka a DVD-RW drive) or get an external DVD burner to burn a longer video.

So I can actually put a "DVD" into a blank CD-Rom?

Sure you can put it in as they are the same dimensions, but nope it will not burn. As Apple System Profiler states, will read and write CDs, but alas read DVDs only. You might like to look at an external, however G4;s being PowerPC, if you want the drive to be bootable, will require a Firewire connection.
