No issues on my PCs, BH200, or playback from my server.
The combination of Dolby True-HD and seamless branching along with the slow random access time of Blu-ray in general, it wouldn't surprise me if this was the result. The slow access time of jumping to different sectors of the disc, even one jump slightly longer than is allowed by the firmware for a valid stream, could result in a drop out. Not all players are created equal, not even on the same assembly line, and there's lots of branching on the Nemo disc.
Try ripping the disc to your computer (if you have a BD drive) using MakeMKV and see if you experience playback issues. At the very least you could rule out the disc. (I highly doubt it's the disc)
