DVD SuperDrive can't be used by Apple Software. HELP!

Question

So a few days ago I replaced the internal CD drive of my PowerMac G4 Quicksilver with a genuine Apple DVD SuperDrive. It works great with regular CD's, and blank CD-R's, but Disk Utility and iDVD don't recognize DVD-R's anymore (not even with my USB DVD drive that supports every type of disc). Disk Utility always says that they are "Read-Only". And iDVD says that a 4.7gb disc is 0 mb.
This doesn't happen however, with apps such as Toast, which knows that it's a 4.7gb blank DVD-R and will burn to it with both the USB and internal drive. Even Apple System Profiler says this:
PIONEER DVD-RW DVR-103:
Firmware Revision: 1.90
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2000 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW
Burn Underrun Protection CD: No
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media:
Media Type: DVD-R
Blank: Yes
Erasable: No
Overwritable: Yes
Appendable: Yes
Whereas Disk Utility says this about the same disc:
Disk Description : PIONEER DVD-RW DVR-103
Total Capacity : 0 Bytes
Connection Bus : ATA
Write Ability : Read Only (DVD-R)
Connection Type : Internal
Capabilities : CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-R, DVD-RW
Connection ID : Device 0
Partition Scheme : Unformatted
And iDVD just complains that [any] video exceeds the maximum size allowed. Upon reading the Project Information like it said to, it says that the maximum size for the disc is 0 mb.
I seriously don't understand what is going on here, I've never had a computer do this kind of thing, where some programs fail after replacing hardware, but some don't. I have a really good repertoire with computers (both PC and Macintosh) but I'm stuck here. I tried all the usual things; Repaired/Verified the disk and permissions (of my Tiger and OS 9 HDD's), checked for a firmware update on the Apple Support Site, but both of those said that I didn't need the update after it finished "installing". Any ideas anyone???

Answer 1

Well of course they dropped it, the drive is almost the same age as the computer haha, which was also forgotten about after only a year before they went on to another model. But even so, the computer originally shipped with the option to have a DVD-RW drive, but it was about $200 cheaper to get it without, and at the time, most people didn't even need the DVD drive. So it comes naturally with the ability to use it.
But I think I know where you're coming from, so I decided to check what iTunes 9 would say about burning to the disc, and it just crashes every time I click "Burn playlist to disc...". So yet another Apple product refuses to work with it.
On another note, even though it's only Apple software that seems to be having issues with it, does it matter? What I mean by that is, the drive works with Mac OS X because of an Extension, and the extension allows applications to use the drive. (The extension for this drive is also natively supported by OS X Tiger) Now, if something were wrong with the extension (one would assume this because of the issues with Apple applications) wouldn't it just not function at all? The only thing I can think of is that the new drive somehow corrupted the Apple software, while leaving ones like Toast Titanium alone.
Just to clarify (I'm still trying to organize my own thoughts right now):
*_What Works_*
*Plays CD-R's
*Can write to CD-R's
*Every application (Apple or Third-Party) can manipulate a CD-R disc
*Can recognize and play retail CD's
*Recognizes DVD-R's in both USB and internal drive
*Third-Party applications (ex: Toast Titanium) can burn to DVD-R's in both internal and USB drives
*Apple System Profiler recognizes the drive, and it's capabilities. And knows that it is Apple Supported/Shipped
_*What Does Not Work*_
*Official Apple software can not burn to DVD's of any kind
*The computer occasionally rejects DVD's (ejecting after trying to load for a while) regardless of the drive
*iTunes quits un-expectantly when told to burn to disc
*Disk Utility says that every DVD is "Read-Only" and has a capacity of 0
*iDVD thinks that the disc is either 32mb or 0mb (changes every time I open it)
