My wife and I own the "Little House On The Prairie" TV Series. We have them on DVD, seasons 1-6, also the pilot movie. Very clean with good morals in the stories. We also have "The Waltons" TV Series Season 1. Again very clean with good morals in the stories plus strong family values.
We also have the following, "Finding Nemo", "Toy Story 1 & 2", "Bug's Life", "Left Behind 1 & 2" although we don't agree with all of the doctrine in the movies. Try looking at the Focus on the Family web site they have a section where they review movies. They break it down by violence, sexuality, langauge and other areas, it is very informative.
