Display MoreI only have Youtube installed, but with M8S+ everything is fine with playback.
It cannot work with kernel 3.10. Amcodec support was dropped from version 19 by the Kodi development team.
If you installed from Kodi 18 repo, this is simply not possible. My opinion is that you have some repo installed that is not compatible with Leia.
Please check the add-on properties:
If you don't see the same thing as in my second screenshot in the update menu, then it is not installed from Kodi's own repository. If that's really the case, I think you should delete the other repo, because it's 100% incompatible with Leia.
As you can see, I have all these versions but noone of them is working
