I apologize if this question is asked before.
When I use 5.8 Ghz video receiver, Windows 8 treated it as a USB webcam. I can see the video working in the Windows 8 allowed app Camera, but when I enable the HUB video in MP, it shows black back ground. It seems like Windows 8 is blocking MP to access this camera. I use the same hardware in an older laptop running Windows 7 with no issues at all.
