Simple Roku Channel ASAP

I'm looking for a simple video grid roku app. 1. Each Row in the grid will be a different category. 2. All Items will be self hosted by me. 3. Need an Xml file to update the paths to the files and meta info( title, description, etc.) 4. Once user select video, Video will load full screen. once done or user backs out, go back to grid. 5. I would supply all design file needs. Thats it. Thanks
