I had many issues with Canola2 and Diablo...I just re-flashed Diablo and re-installed from Canola's website and while everything is now working, it will not go into full screen as it does with the native N810's video player. SO I use Canola for music and pictures and the native N810's video player. The Canola website has all the steps you need to install so you might try uninstalling and then install directly from Canola.
