vmcMote is an App for iPhone/iPod Touch that let you remote your windows media center! vmcMote HD is a special iPad version of vmcMote.
As opposed to your normal infrared-remote and the most remotes you can find in the Apple AppStore, vmcMote is a two-way remote: It not only sents commands, but also gets information back from your media center about the its current state!
It enables you to browse the music library, search for music, play/enqueue tracks, view the currently played music track, the current playlist (and on Windows 7 also the currently played video), navigate inside the current track, create and manage playlists (on device only). And you can do all of this with your Tv switched off! Furthermore, a simple remote functionality is included for cases when the Tv is on and you need some basic remote functionality.
