@beinos, for your addon start problem:
- Do you have a static ip? I had the same problem when i set a fix ip, kodi start thinking the network connection is ready but it is not, only the ip is set and the boot sequence will continu, but the router did not finish the initialization! So pvr start with an error. By using dhcp no problem, because you will get an ip when the router will respond and give is own ip address, and the boot sequence will continue only after that
Hope it'll help, good luck!
