 I've been seeing the same problem on all 3 of my Nvidia Shield TV 2017s. The addon works and all files play fine when played on an Intel NUC5I5RYK running windows 10. I've pulled a debug log from one of the Nvidia Shields where files pause after a few minutes of play and then just quit (I don't get a source too slow error message). Here is the debug log

That would mean the issue is in the Nvidia side, as stated before. But if someone can find something useful that the addon can do, it will be welcome. 

That's where I'm leaning towards now after doing more testing and switching back to playing the same media off my local NAS.
