iOS app to download YouTube videos to video library? I have an iPhone 3GS with iOS 6 an I would like to watch movies on the TV, therefore I bought an AV composite cable. Only videos that are located in the "photos/videos app" can be played on the TV through the AV cable. Is there an app that can download videos from YouTube to that folder?
It's always a bit tricky to download anything on iOS devices..

When I want to download a youtube video I open the YouTube video in my browser and add "dlv" in front of youtube so that it reads www.dlvyoutube.com and there download it.. Then I transfer it over to the device with iTunes.
