I've been researching this more. This particular drive is recommended by many places and I've read a couple dozen reports from people who have put these into old and new Macs successfully. Some had trouble with the master/slave situation and Master should be the correct one for your DA as long as it is on the secondary IDE channel and not on the main drive channel.
I did find several mentions that the drive was very slow at mounting discs. Have you waited long enough for them to mount?
Also found some System Profliler reports from people using 10.4 and yours should be similar. Note that some have newer firmware than your and there is a very recent one but you can't upgrade the firmware from your Mac. You would have to either put it into a PC or an Intel Mac running Windows.

Found this Terminal command for forcing CDs to mount:
sudo mount -f -t ufs Also came across a suggestion to boot into Open Firmware to check the physical status of the drive:
Booting into open firmware (hold apple+option+O+F on boot) and when you get the white screen of text, insert a CD. (at this point we have isolated the hardware alone, no software is playing into this test) If THAT ejects the disk, the hardware is not recognizing the disk and is defective. If it happens to keep it, type
eject cd to eject the disc and try a DVD.
shut-down to shut down the computer after you're done testing.
(You may have to put the CD into the drive first, then restart into Open Firmware)

Lastly, do you have an external FW case you can put this drive into? That would be one way to check if the interior cabling/jumpers, etc. are causing any problems. My DVD burner is an external FW.
If all this fails, I'd send it in for a replacement.
