Thanks for this, I've had some really bad buffering issues with nearly all of my add-ons lately, but this one is working perfectly, and the picture quality is excellent.
Download Aptoide in the app store, open Aptoide and search for Show Box, good selection of movies many in HD, no buffering, but the movies are broken into 15 minute parts, so every 15 minutes the screen will go black for a few seconds, then continue.
I got my Android box on Sunday and I've been pulling my hair out with it since it arrived. I went with the more expensive option because I read that you get what you pay for. I've had nothing but problems with buffering and stopping and starting. Was just about to pack it all up and send it...
