Public bug reported:

Totem's DBus-plugin may have a bug.  I try to control the Totem-player
from Audio-Recorder.  Audio-recorder does see the player on the DBus but
Totem does not reply requests.

This same bug was reported last year too. And year before.  Now this annoying bug is back!  
What the H* are they doing?

I run totem 3.16.2 on Ubuntu 15.10 (alfa).
$ totem --version
totem 3.16.2
--------

Totem fails to return "PlaybackStatus". (this is a long one-line
command):

$  dbus-send --print-reply --session --dest=org.mpris.MediaPlayer2.totem
/org/mpris/MediaPlayer2 org.freedesktop.DBus.Properties.Get
string:'org.mpris.MediaPlayer2.Player' string:'PlaybackStatus'

----------------------------------------------------

Good samples:
Here are correct replies from the RhythmBox player:

Get Playerstatus from RhythmBox:

$ dbus-send --print-reply --session
--dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2
org.freedesktop.DBus.Properties.Get
string:'org.mpris.MediaPlayer2.Player' string:'PlaybackStatus'


method return time=1441188372.041001 sender=:1.146 -> destination=:1.149 serial=194 reply_serial=2
   variant       string "Playing"
-----------------

And get Metadata from RhytmBox:

$ dbus-send --print-reply --session
--dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2
org.freedesktop.DBus.Properties.Get
string:'org.mpris.MediaPlayer2.Player' string:'Metadata'

method return time=1441188535.630312 sender=:1.146 -> destination=:1.161 serial=226 reply_serial=2
   variant       array [
         dict entry(
            string "mpris:trackid"
            variant                string "/org/mpris/MediaPlayer2/Track/2"
         )
         dict entry(
            string "xesam:url"
            variant                string "http://ubuntu.hbr1.com:19800/tronic.ogg";
         )
         dict entry(
            string "xesam:title"
            variant                string "After Midnight Dejavu (2006)"
         )
         dict entry(
            string "xesam:genre"
            variant                array [
                  string "House"
               ]
         )
         dict entry(
            string "rhythmbox:streamTitle"
            variant                string "HBR1.com - Tronic Lounge"
         )

....
....

BTW: I can see in the Audio-recorder (when debugging) that Totems sends
some DBus-messages repeatedly. Audio-recorder gets mad by receiving 20
STOP, START, PAUSE, START, STOP, PAUSE, STOP... messages.  I programmed
a special workaround for Totem in Audio-Recorder.
