Yeah, i read through your site, and i think that your goal is not quite what i need - i want a media player entirely accessable by keyboard! Haha
I dont have touchscreen, and i'd rather be able to control my media with a numpad (mapped with Girder); as i will be able to do that without looking at the screen (same way i can use my regular stereo without looking at it).
I do like the simplicity of it. But do the modules run concurrently? (i.e. can you start your navigation, switch back to the menu and launch DVD to have both running at the same time (so you can switch betweeh the two to see how you are going etc))
