That is the dumbest explaination for the switch from flippers to two disc sets I have ever heard. It has nothing to do with idiot proof, and more to do with people wanting nice looking sets instead of lame two sided discs. 2 sided discs are also a lot more prone to damage, especially when you have siblings, kids, room mates, or whoever who tend to toss the disc on the top of the DVD player instead of putting it back in the case. And seriously, it is not like it costs a whole lot more to produce a set with two discs as opposed to a flipper.
