Some Kodi optimization hint: I'm usally playing files only from my home-made NAS server (WHS 2011), no local media. I just played around and was surprised how smooth is runs in comparision to the X9 box ... Anyway I still get buffering while playing files with a huge bitrates. My "high-end" test scenario is the waterfall scene at about 27:30 min. of the Avatar BD (untouched) which delivers about 68 Mbit/s at peaks. As expected I got that buffering ... playing 30 seconds and got buffering ... So I tuned Kodi with the cache settings and it is running much better. Not 100% without buffering but better The waterfall scene is playing fine now, at some certain chapters with high bitrate over a longer period buffering is still present. These are the settings I'm using now: Code: <advancedsettings> <network> <buffermode>1</buffermode> <cachemembuffersize>80943040</cachemembuffersize> <readbufferfactor>30</readbufferfactor> </network> </advancedsettings> Put these definitions into a file named "advancedsettings.xml" and transfer it to the Kodi user data folder /sdcard/Android/data/org.xbmc.kodi/files/.kodi/userdata/ You may download the file from google drive as well: https://drive.google.com/file/d/0B1q2CGHGzNsFOHNSei1pLTEzT1k/view?usp=sharing In case you don't have a ftp server to transfer the files to the box I could recommend to install the ftp server from the playstore (easy to configure and use) https://play.google.com/store/apps/details?id=com.icecoldapps.ftpserverultimate PS: I assume 2 GB of RAM would be the key ...
