So the 'driver' in the feed is for dreamboxes only?
I do not know about the driver, i think it is just Sundtek Control Center which is not compatible with Vu+.
I do not have OpenPli now installed so i cannot check if Control center is or is not compatible with Vu+, i cannot remember which version it was.
from Sundtek:
Some Dreambox Sundtek Control Center versions are not compatible with VU+
