Hi Fred,
Thanks for your interest. Yes, please do download the trial and try it out. The scenario you describe (with the repeating tables) is supported and the example that comes with the tool shows the mapping required for this.
I'm not sure what you mean by "2 text boxes with person picker control" (are these Text boxes or People Pickers?) Remember that if mapping into a People Picker, there are three fields in the form that need to be filled out (mapped).
Good luck, let us know how the trial goes.
