DTV is basically AutoCAD without the ability to add content: so explain in more detail what AutoCAD is using for a plotter driver (or PC3 file) and if that is identical in DTV to start with.
DTV on it's own will not find PC3 files in use by AutoCAD, you have to actively make them available for example.
