Hi, I have this:
MVISION 9080 USB
Slot 1: Diablo rev. 2.3 + Underworld 163
Slot 2: Dragon rev. 3.02 + Predator 3.69
When I insert them in the receiver, both appears in menu, but within a few seconds, the Diablo disappears. Are they incompatible? Cannot be connected simultaneously? I am surprised, because separately, they work correctly!
