Oh ok! Pardon me. Disks are in the hopper, none in the drive.
I have a cygwin environment w/bash shell script that generates and calls the supplied command.
Imgburn loads up, I see it searching for robots, then the Nimbie does the eject tray, close tray, eject tray bit, then drops a disc onto the tray, tray closes, anydvd hd does its thing, then imgburn does its read init, and then things start going.
