Is there a way to open 2 video windows?
If there is, I'm not aware of it. The method that I've heard of people using is pretty much as you describe in (2), but with a VGA splitter on the second monitor, and you run two monitors for the second screen, so that all parties involved can see the video. Clearly it's not perfect, for the reasons you describe, but it's a lot better than the operator not seeing the video at all.
