Thanks, Marty.
Flashed the Verbatim 43888 back to 1.03 (including "enc" in the command) - all worked - movies are flowing!

Excellent.
One more Q: The existing BU40N-1.05 on the drive is not on your list of known encrypted firmware so far. On the makemkvcon64 command, do I need the "enc", or leave that out?
Thanks!
