Media Remote is software that enables you to remotely control media (MP3/Video) playback on your computer.
It is created to enforce laziness - using Media Remote on your Smartphone it is possible to change song that is playing on computer from comfort of your bed. Also it can be handy if you are living in duplex home and have speakers all around house (I envy you) and want to showoff.
Remote control of video playback is one additional useful functionality that comes to mind.
To run it you need to install .NET Framework 2 on your your computer and mobile device while having Winamp as default MP3/Video player.
