at first, thaks for Ventuz4. Thanks for your great work

There are 2 SDI Boards in my pc: Blackmagic Design 3D Extreme and DVS Atomic LT board.
In AV Configuration in the Ventuz4 PLE software there are icons for nVidia, Blackmagic, NewTek and Off-Screen but no DVS icon. What's wrong? Is there any different driver nessesary in Ventuz4? In Ventuz3 I can choose both, Blackmagic or DVS...!? If I choose Blackmagic in Ventuz4, fill and key will be shown as well on the SDI fill and SDI key out of the Blackmagic card.
Best regards
Bernd
