Tvheadend

Hi!
Recently I switched one of my media centres from XBMC 12 to 13 and Transcoding stopped working. On the other computer that is connecting to the same Tvhedend, transcoding is still working. So it seem to be a problem with the pvr addon of XBMC.
I guess the problem has something to do with the seddings.xml of the pvr addon.

When transcoding is enabled and I choose a channel, XBMC starts buffering and nothing happens. Tvheadend tunes to the wished service, but then nothing happens. I also don't see any errors. Neither in the xbmc debug log nor in the Tvheadend log.

Here are my settings.xml

XBMC 12, still working:

<settings>
    <setting id="audio_codec" value="0" />
    <setting id="connect_timeout" value="9" />
    <setting id="host" value="127.0.0.1" />
    <setting id="htsp_port" value="9982" />
    <setting id="http_port" value="9981" />
    <setting id="pass" value="pass" />
    <setting id="resolution" value="480" />
    <setting id="response_timeout" value="4" />
    <setting id="transcode" value="true" />
    <setting id="user" value="xbmc" />
    <setting id="video_codec" value="28" />
</settings>

XBMC 13, not working:

<settings>
    <setting id="audio_codec_name" value="0" />
    <setting id="connect_timeout" value="9" />
    <setting id="host" value="192.168.5.2" />
    <setting id="htsp_port" value="9982" />
    <setting id="http_port" value="9981" />
    <setting id="pass" value="pass" />
    <setting id="resolution" value="480" />
    <setting id="response_timeout" value="4" />
    <setting id="transcode" value="true" />
    <setting id="user" value="xbmc" />
    <setting id="video_codec_name" value="0" />
</settings>

Does anyone see problems with my settings.xml?
Could someone please post a working settings.xml from XBMC 13?

EDIT:
Finally I found some differences in the debug log of Tvheadend:
