"Record both cameras" checkbox behavior

[Cody-G]

On the waveform branch if I check that box and press record while using two cameras there is a problem if recording files already exist. I get the "do you want to overwrite" dialog. When I click yes on that dialog, the camera immediately begins its recording sequence without waiting for the other camera (which also produces a dialog box when its files exist).

We could not reproduce this error yet. But need to keep watching.
