[bsoriano]

@bsoriano thanks anyway. consulted the log with corelec admins, they claim the skin. interesting that no problem on other skins, but i love yours :-)
i tried to remove some other addons and ended up reducing the log to minimum errors, but still same behaviour. hereinafter log with reduced errors, still nothing suspicious from your point of view?

@nrpetonr , the error I see with pvr at first glance does not seem to be skin related.  The only thing that comes to mind is that when an item is playing and you are in the home screen, Amber tries to show fanart related to that item, including extra fanart.  If there is no multiple fanart for the item loaded in the db, Amber tries to find it in an /extrafanart/ folder.  This seems to be giving an error with the PVR client that you are using.

Could you please test the latest from GitHub? https://github.com/bartolomesoriano/skin.amber   Master branch is for Matrix.  Please let me know if this solves the issue.  Thanks.

Regards,

Bart
