ClearPlay and do you need it?
ClearPlay is billed as “a revolutionary way for your family to enjoy movies”. As you can see from the video, it allows users the power to remove objectionable content from movies that they watch on a DVD player.
You have to get their DVD player in order to do this, but you can use DVDs that you rent or own. Then you have to insert the FilterStik into the USB port. Apparently, you need to download this filter based on the specific movie. Filters are obtained by forming a membership, and you will have unlimited access to their selection which includes filters for television and movies.
