Youtube Downloader

[Covert2String]

Hello, I was wondering how apps like Atube catcher, etc worked so I decided to google it. The problem is everything is outdated and I'm not able to find out how youtube "protected" direct download links. Ideally some explaning would be great, i'm not looking for the exact code. Brandon to the rescue, please? <!-- s --><img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt="" title="Very Happy" /><!-- s -->
