@JulioJS: I'm not sure if you're still maintaining this wonderfull app, but if you still are, I have a new feature proposition for you.
Now that firmware 0.5.2.1 has been released, the
webscreenshot.app.bin should work fine on Live/Plus devices (and we're still working to bring it to Gen3 as well), I think a great new feature for your app would be to have the ability to see the output of the app.bin (the OSD screenshots) directly in your app as you're navigating. This would allow easy navigation and feature selection when operating the WDTV without a TV open.
Let me know if you need help (I will supply the URLs needed to fetch the images).
