@axbmcuser, would you be OK with me adapting your code to show the video info dialog from a button in the OSD?

Hey, sorry for the late reply. Life....

Sure, thanks for asking. Feel free to adapt the mentioned code for your own skin work. The solution works very well.
 

I noticed you are not including (yet) this functionality in the Matrix version of your skin, is that because library.data.provider.lite does not work in Matrix?

Yes, that's correct. The Matrix version was/is just a quick alpha release which hasn't been worked on yet any further. I wanted to wait until the regular "library.data.provider" is updated for the new python version and then work on my "library.data.provider.lite" version based on that.
I think "library.data.provider" will be ready by now.
Only problem is that i don't use Kodi Matrix on any system yet and therefore have only worked on my main version for Krypton (and Leia).
Work will resume sometime! :-)
