I was looking for solution to the issue of these new versions of Plex Media Server to the DNS-320L/325/345 (ARMv5 processor) models, but I found A formal statement Plex developers, the latest version for ARMv5 - v.0.9.14.x.
It was v0.9.17.x assembly for ARMv7 with "soft float", which can run on ARMv5. But it is for the "Plex Pass". I have no "Plex Pass" (no need), so do not gather. Although, I have the opportunity and the desire to do this. Who has the "Plex Pass", can pull and give me v0.9.17.x for QNAP ARM, will receive a free add-on.
Apparently, not only me, but first and foremost developers of Plex tired questions "why so slow", "why not all of the files shows," "why and why ...........". The same issues in a large number every day - this is the result. While all FAQ-s big letters all written ... As a result, people have rejected possible earnings in exchange for peace of mind. Whatever this is my personal opinion, I do not see any other explanation.
