Special Announcement: QNAP CodexPack 4.5.0 Issues with PMS



This announcement is due to a major bug introduced by QNAP's CodexPack vers 4.5.0 and how it disrupts normal PMS operation.

For those who are using the Multimedia library, introduction of CodexPack 4.5.0 breaks all access to your media in PMS.

Your normal media access, which was defined through Multimedia is disrupted by the CodexPack incorrectly and inappropriately injects itself into that path internal to the Multimedia share mechanism.

Your previous path to 'Movies', which previously was in /share/CACHEDEV1_DATA/Multimedia gets altered.
After installation of 4.5.0, your path now looks like /share/CACHEDEV1_DATA/.qpkg/CodexPack/mnt/share/CACHEDEV1_DATA/Multimedia which does not work because PMS does not know of that path.

It is understood CodexPack is required to use HD_Station and other QNAP apps.

To remove your PMS installation from this problem and prevent any future involvement with it, it is strongly suggested to access the shares directly.


  • Previously shares animated, horror, scifi, and comedy as part of Multimedia/Movies
  • PMS was accessing them through /share/Multimedia/Movies.
  • In Libraries -> Edit, for each Library section, add each share directly into the list of folders for PMS: /share/animated, /share/horror , /share/scifi, and /share/comedy
  • Do NOT remove the 'Multimedia` entrie(s) at this time
  • Allow PMS to scan your media and find it again. This happens automatically after Editing a Library section
  • PMS will show a duplicate (2) for each item as it finds it again. This is expected and desired.
  • After scanning is complete, verify all media has been found. Resolve any missing items
  • Return to Libraries -> Edit for each section and remove (x) the Multimedia based folder definitions
  • As PMS scans the section one final time, observe the 2 being removed.
  • The watched status and metadata will be intact for any items not previously lost by the installation of CodexPack 4.5.0

The TL;DR is

Only use /share/ShareName (from the left pane) or /share/PoolName/ShareName (using two-step left/right panes) in Plex. Let Multimedia and CodexPack do what it wants to. Keep PMS free and clear of it.


If QNAP tech supports attempts to assert PMS is corrupt, refute, do not accept, the answer. it is 100% CodexPack failure, not PMS.


Update: 19-Sept-2017

Telephone conversation with QNAP tech support (California, USA) confirms

  1. Use /share/ShareName or /share/PoolName/ShareName (e.g. /share/CACHEDEV1_DATA/ShareName) as they both go to the same place.
  2. If you experience this difficulty with CodexPack and Multimedia, send in a HelpDesk ticket about it.
