Path Redirect Not Working

Hi All,

My Shield is running out of space so I need to get thumbnails to my smb server. For some reason, the following isn't working:

Advanced:


<advancedsettings>

  <videodatabase>

    <type>mysql</type>

    <host>xxx.xxx.x.xxx</host>

    <port>****</port>

    <user>****</user>

    <pass>************</pass>

    <cache>

      <buffermode>4</buffermode>

      <memorysize>62914560</memorysize>

      <readfactor>5</readfactor>

    </cache>

    <pathsubstitution>

      <substitute>

        <from>special://profile/Thumbnails/</from>

        <to>smb://xxx.xxx.x.xxx/Expansion2/Thumbnails</to>

      </substitute>

    </pathsubstitution>

  </videodatabase>

  <musicdatabase>

    <type>mysql</type>

    <host>xxx.xxx.x.xxx</host>

    <port>****</port>

    <user>****</user>

    <pass>**********</pass>

  </musicdatabase>

</advancedsettings>

I have my samba set up in sources and password xmls and confirmed that I can access them fine in Kodi.

Thanks in advance.
