I'm running a BlackMagic HDExtreme card for my preview out monitor and the option for using this card as well as the Windows Secondary display and OHCI compliant are all in the Preference>Preview Device section of Vegas 8.0 but the BlackMagic option is NOT being found in DVD Architect. The Windows Secondary and OHCI compliant choices are in the DVDA Prefs>Video Device drop down but not BM. Does anybody know why or if I'm missing something?
