Kidz Vidz Lite
iOS Universal Entertainment
A simple movie playback for Kids! Supports playback of .mov, .mp4, .mpv and .3gp files from your uPNP or DLNA media server.
Parents can set the folder on the media server so kids don't need to choose. The folder selection is protected by a PIN code so kids can't change folders without permission.
iPad, iPhone and iPod touch supported.
Try the Lite version to see if it works with your media center. The Lite version is limited to displaying 3 movies within a folder.
