Screen turns black when I start recording using MIP SDK

I have 3 cameras attached to a server. For some reason, on one of them (Sony), if I press the record button it will cause the screen to go black. Any ideas why this could be happening? Thanks.

I also noticed that the live video flickers (it turns black for half a second) sometimes while watching the live feed.

You mention a record button, is this button in the VideoViewer sample?

Please elaborate on how you make the observation. Do you see the same behavior if using the Smart Client?
