any idea where to find the userdata folder to include the advancedsettings.xml in ZDMC?

Yes, and I tried to use the advancedsettings.xml with the ZidooPlayer to no good effect. You need to place the advancedsettings.xml file in the Android/data/com.Zidoo.zdmc/files/.zdmc/userdata/ folder. But when I tried this there was no improvement in buffering issues when using the ZidooPlayer (external player). In fact playback was actually worse.

And no matter what I have tried, the current firmware has significant buffering issues with MacOs Sierra or El Capitan, even from a newly created clean installed boot disk without any additional programs added. NFS performance is sluggish with constant buffering issues. SMB from MacOS as a server is better, but spotty and unreliable in playback. However SMB under a windows virtual machine from my MacPro works most of the time, but has significant audio sync issues.

Since I purchase this replacement Zidoo X9S after November 1, 2016 from Amazon Prime, I have until January 31, 2017 to return the player for a complete refund. So I will wait and see if they release a firmware update to fix these buffering issues, especially with NFS before returning the player as a complete loss.
