[Coco] How do I copy a DMK formatted virtual disk to a JVC virtual disk?

[Bert & Peggy Schneider]

I'm getting all of my CoCo software copied off my PC and onto 3.5"
floppies.  My only problem now is that my CoCo doesn't seem to be able
to read, nor can OmniFlop copy DMK formatted virtual disks to my 3.5"
floppy.  Perhaps I need to add some more formats to my OmniFlop
registration?
