Hi Scott,
The IDeckLinkDX9ScreenPreviewHelper has it's own transform function implemented, so it will override attempt to call SetTransform externally. However, it is possible to rotate the preview by 180 degrees (in case camera is mounted up-side-down), by swapping left/right and top/bottom coordinates of the viewport rectangle.
For flipping, the solution will be to either:
1) Iterate through frame lines and manually swap lines (CPU intensive).
2) Implement own DirectX or OpenGL helper to perform own custom transforms.
Regards
Cameron
