hei jdearana,
i wouldn't know a extra for your problem. but you might want to look at pixelpark.com.
as for the videos. i usually use qt (which is quite common on the pc aswell). then you get the qt installer (for both mac and pc) and put it on the cd aswell. on loading the movie, check if qt is installed, if not, advise the user to install qt first.
wouldn't know any other way.
