It took me a while to grasp what you meant with your second question but I think I got it.
A picture as you posted it typically results from a bad video codec which, and I guess, everyone who has successfully recorded a video from within Plant Simulation will agree, the default Microsoft code is. We had pretty positive experience working with the XVid code which you can download freely - just search for it.
This pretty certainly will fix what you describe in your first question.
And I guess, it will "accidentally" fix your second problem, too, which, if I am correct, is simply another symptom of the same problem (i.e. the codec).
