Thanks for the tip, my niece has (children's content) Netflix on PS3 for her two toddler girls. They have NO other television because it is crap. I'll tell her to keep an eye out.
With the "upgrade" now the interface on the BluRay player allows "surfing" of all their selections. You can controls on the ratings, but a lot of their kids stuff doesn't have a rating and get blocked if you put a "G only" restriction on your account. When you restrict, you restrict all your devices as well. I like the old setup better.
