Slow transfer under NVIDIA Shield

Hello,

I’m using Kodi 16.1 android under an NVIDIA Shield player, connected to a Synology NAS device (4-drive RAID) via Gigabit ethernet.

The problem I’m facing, is when I play an mp3 in the background and I try to access my photo collection, the mp3 playback starts to break up. So its impossible to start a slideshow with some background music.

Anyone seen this issue before? Is it a bandwidth problem with the Shield, or is it an issue with Kodi?

Thank you.
