vmcMote is a iPhone/iPod Touch app that allows you to control Windows Media Center. It’s available in the iTunes store for $7.99 or a lite version for free. I would always try out the free versions first to test things out. It has some built-in functionality for queuing up media but also has a remote pad to completely navigate around Windows Media Center. The video below from TheDigitalLifestyle gives a overview of how the app works.
