One of the first apps we loved was the iTunes Remote-now, the Swiss army knife of media players VLC has one of its very own.
While it can't quite match the music library organization skills of the more OCD iTunes, VLC will play just about any video file in the world, ever. So if you're streaming video from your computer to your TV or using VLC on your home theater PC, control is now a lot easier.
Regular version Free, Full version $3
From The App Developers: VLC Remote lets you remotely control your VLC Media Player on your Mac or PC.
