Hum. I created encrypted DVD years ago with a similar procedure, 
somewhat simpler. Basically, I created an empty file of the same size as 
the CD or DVD, mounted it as a loop device, then I encrypted that loop 
device, and then I formatted the resulting luks device with any 
filesystem type I wished, typically XFS.

This, so far, still works.

Then I just burn that file to DVD.

The final step is to mount and decipher the DVD - and this step failed, 
but it was an XFS error if I remember correctly.

I can fish out the precise instructions if you are interested, and find 
out the actual error. I have a bugzilla stuck on it.
