Most noob friendly video editing software featuring Picture-in-Picture?

I saw that 90% of the thread around here is about the best video editing software, now, I'm doing great with Premiere Pro, my question is which video editing software with PIP functionality would you suggest to a total noob (I want to teach to my VA some basic videoediting but introducing her to Premiere Pro would be overwhelming).

Unfortunately googling around I didn't have much luck, and the most known basic videoediting software (i.e. Windows Movie Maker) don't include PIP.

Thanks in advance!

Check out CyberLink PowerDirector 13 Ultra. Its the best one.
