I took one of Nevo's pre-built samples and I turned it into an Apple TV-esk like interface using the AppleTV button. The configuration is still step up as a template so you can use the Super Fast Device swap feature in NevoStudioPro. To use the interface, you can use the touchscreen and touch the button or any of the labels or my fav - use the cursor pad on the Q50 to scroll between selection of Watch TV, Watch Movie etc and use the OK Button to select and start the activity.
I designed this program around an activity based setup. My Dad comes to visit regularly and he couldn't figure out how to use my system with my old remote - I tried to make it as user friendly as possible and I think I accomplished that goal - I know my Dad never asks me how to use the system anymore - I didn't even have to show him what to do with this setup. I made it extremely easy to change channels by using the Channel Logos as the main interface to change cable> channels instead of using the digits. Right now - it has a Rotel processor but early next week I'm replacing that with an Atlantic Technologies Processor. I'll post an update when complete.
