DVD Writer not recognized

Did not know which forum to post in, but I installed the DVD writer to make backups....
OK. I took a Samsung USB DVD writer off a Centos server where it was used with cdrdao as /dev/scd0
I installed K3B on my AMAHI and started K3B. It reports no CD/DVD writer found.
So I put a Audio CD in and run the command:
cdrdao read-cd --device /dev/scd0 --datafile My-CD.bin My-CD-toc
And this reads the CD and creates the .bin and toc files just fine.
So what do I have to do to get K3B working on my AMAHI server so I can do DVD backups?

Perhaps a hint to the problem. For writing an audio CD (from what I previously read) I needed:
cdrdao write --device /dev/scd0 --driver generic-mmc-raw My-Turn-toc
I did not need the generic-mmc-raw driver for the previous system I used it on....

OK. I also see /dev/dvd, /dev/dvdrw, and the symbolic link: /dev/sr0
I tried to add all of these as devices into k3b, and it did not recognize the device.

bad drive?
bad cable?
bad disk?
something's not quite right ...

bad drive?
The cdrdao command works. Reads fine. Write requires the generic-mmc-raw driver.
bad cable?
I can try a different one, but doubt this is it.
bad disk?
I get the error with no disk. And on my notebook, k3b starts just fine with no disk. further, when I had the audio disk that played just fine and ripped just fine in, k3b gave the error.
something's not quite right ...
Yeah. Exactly.
