Hi - Using the trial version of Mezzmo and I was wondering if were possible to set it so that it transcodes Apple lossless as PCM? At the moment the profile transcodes as mp3. I changed the profile I was using to the Integra DHC one meaning I can stream to it as PCM, but this then throws out the video play back (mp4 has a hissy fit). It also doesn't pull across the track details (name / artwork / running time etc). If you could amend the Denon 2012 profile so it outputted PCM, or point me in the direction of how to do it...

Cheers!

Hi,
if you open the Integra DHC profile in a text editor you will see a section:

<avcontainer id="s16be" name="lpcm" encode="1" mimetype="audio/L16;rate=44100;channels=2" baseline="1" dlnaprofile="LPCM" preferredtranscoded="1" supportschunked="1" format="s16be">
<audio>
<format id="s16be" encode="1" codec="pcm_s16be" preferredtranscoded="1">
<channels>2</channels>
<bitrate>1536000</bitrate>
<maxbitrate>1536000</maxbitrate>
<minbitrate>8000</minbitrate>
<maxsamplingrate>96000</maxsamplingrate>
<minsamplingrate>8000</minsamplingrate>
<samplingrate>24000</samplingrate>
<samplingrate>32000</samplingrate>
<samplingrate>48000</samplingrate>
<samplingrate>64000</samplingrate>
<samplingrate>96000</samplingrate>
</format>
</audio>
</avcontainer>

If you copy this and then open the Denon BDP 2012 profile and replace the following:

<avcontainer id="mp3" name="mp3" encode="1" mimetype="audio/mpeg" dlnaprofile="MP3" preferredtranscoded="1">
<audio>
<format id="mp3" encode="1" codec="libmp3lame" preferredtranscoded="1">
<channels>1</channels>
<channels>2</channels>
<maxbitrate>320000</maxbitrate>
<bitrate>320000</bitrate>
<maxsamplingrate>48000</maxsamplingrate>
<minsamplingrate>22050</minsamplingrate>
<samplingrate>48000</samplingrate>
<samplingrate>44100</samplingrate>
<samplingrate>32000</samplingrate>
</format>
</audio>
</avcontainer>

You will get audio transcoded as PCM instead of mp3.

Device profiles can be found in c:\programdata\Conceiva\Mezzmo\DeviceProfiles or c:\documents and settings\All Users\Application Data\Conceiva\Mezzmo\DeviceProfiles
You will need to restart your Mezzmo media server after saving the changes to the device profiles for the change to take effect.

Thanks very much. I'll try that as soon as I get my player back from it's hopefully brief visit to the repair shop....
