Got a problem with my mimimosd.
I have a hobbyking FPV switcher inline with my gimballed gopro, and my pilot cam (sc2000 - the one everyone buys). The minimosd sits between the fpv switcher video out, and the tx.
The problem is that I get a perfect overlay on the gopro view, but no overlay when using the sc2000. Both cameras work perfectly, as does the fpv switcher.
The camera is 12v (powered from12v BEC) the gopro 5v, and telemetry is 5v too. I only output video and ground from the 12v camera into the FPV (and therefore into the minimosd).
What am I doing wrong? Why no overlay on the 12v?

Bit of a bump on this one.
Here is a picture of my setup. I cannot work out why the OSD does not display when the board cam is running. If I unplug the camera's video from the FPV Switcher, the OSD displays ok! Plug it back in...perfectly good video, but OSD is gone. OSD runs no problem when switched to the GoPro.
As mentioned above - both camera's work fine, the FPV switcher works fine with both cam and the OSD works fine...as long as the board cam is not plugged in. I suspect it's because the board cam is 12V, and the Gopro is only 5V. The minimOSD is unchanged in any way....does version 1.1 allow me to mix voltages? Is the voltage mixing the problem maybe?
Nope! I ended up getting a v1.1, and it seems to be better!
