I am having the exact same issues with my rpi 3 using raspbian with Hyperion installed on it. It's really annoying.. my question is: is this delay always present when using a grabber or is there any way to get rid of it? I don't get, what the IP Adress has to do with it.. I am not using Kodi and don't plan on using it in the future.. the Lightberry is supposed to work together with my NVIDIA shield.
