Roku Controls With PowerShell

This is a GUI I created that will interact with any Roku boxes that may be on your network.  Not only that, I was able to figure out how to convert some c# to PowerShell to send out SSDP broadcasts for network device discovery.  This enables the GUI to discover any Roku boxes without having to know the IP address off hand.  It is not complete, but works well.
