GreenForce-Player

GreenForce-Player is a small audio and video player that stands out for its ability to add protection to your files with just a click. You can password-protect them, encrypt them, and even shield them from screen captures, if you wish.

Other, more standard features include creating playlists, setting different visualizations when you're playing music, taking video screen captures, and easily changing the aspect ratio.

There is a wide range of supported video formats, including all of the most popular formats as well as some that are more obscure, like AIF, RA, AAC, and MPA.

GreenForce-Player looks a little like the popular VLC player, and although it offers a much smaller amount of features, it does come in handy when you need to lock (and unlock) multimedia files using DRM.
