CBS Children's Film Festival

This was actually a long-running series on CBS that each week featured a wonderful movie that I watched with my kids. Now I would like to find those movies to play for my grand-kids, but without more information, I am at a dead end. Is there any possibility that CBS has some sort of archives in which the old movie are stored and from which they could be retrieved? If anyone knows, how about a post? I recall a particularly poignant Russian film about a dog named Chip. It had me balling like a baby, along with my 6-year old. And that wasn't the only one. Like I said, I recall this as very wholesome entertainment that we could trot out again for the 5 - 10 year old generation.
