Powerbook G4 and DVD-RW

[annk]

This is most likely a very basic thing - I´ve searched but haven´t found anything that gives me exactly the answer I´m after, so if this has already been discussed I´m sorry for bringing it up again...

I have a 1.5 GHz PB with this superdrive:

MATSHITA DVD-R UJ-825:

Capacity: 7.68 GB
Manufacturer: MATSHITA
Model: MATSHITA DVD-R UJ-825
Revision: DAM5
Serial Number:
Drive Type: CD-RW/DVD-RW
Disc Burning: Apple Supported/Shipped
Removable Media: Yes
Detachable Drive: No
BSD Name: disk1
Protocol: ATAPI
Unit Number: 0
Socket Type: Internal
OS9 Drivers: No

I can burn DVD-R fine. I´ve also burned onto DVD-RW fine, but when I want to burn over them, the drive won´t accept them as writable.

I´ve searched around a bit, and found conflicting info, not all of which I understand completely. I think I´ve understood that I need new firmware to do this, but that adding firmware when you don´t know what you´re doing can mess up the drive completely and void the warranty, and I´m not willing to do that.

So what´s the deal? Do I have to somehow erase the discs? Is new firmware (or a new PB) the only option to do what I want? Or can´t my drive burn over previously burned DVD-RWs no matter what?

Powerbook 12 inch

I have the same question about my 12 inch powerbook with a superdrive 1.5 ghz will I be able to rewrite on dvd's if so what kind of dvd's do I need.
This is some confusing stuff.
Thanks in advance all of the macrumorers are always so help full.

Yes you need to erase them you can do it in toast (costs money) or disk utility (free, came with your mac).

In look in Your HD/Applications/Utilities/Disk Utility open it up. On the left you will see all of the drives connected to your mac click on the CD (the top most CD) then click on the erase tab and click on erase.
