Hi, the updated playercorefactory works for me. Many, many thanks.
In any case, Kody 17 is a very poor version of Kodi 16 with a lot of performance problems, of ourse, no Himedia problems. But it could be a good idea to create a Android N firmware with Kodi 16.1 at least meanwhile Kodi 17 is not be stable.
Thanks for your support again.
