Yes, that was my fault, like Eric pointed out. It works now. I wanted to use 
2048, but I didn't see my typo. 

Now I could create a geli encryptet DVD. I create a file backed memory disk. 
Then I create an ISO image. I put the image on the memory disk, then I burn 
the file on the DVD. Now I can attach the DVD and the ISO file system is on 
the attached device.
