Panasonic TV TH-P50V2

It's a TV for the Japanese market (because that's where I live), from 2010. Plasma screen, 50 inch.
The serviio server 1.4.1.2 runs on a CentOS 6.5 box. I can watch videos with a DLNA player on my ipad, but the TV acts up.

Symptoms:

• Selecting the out-of-the-box profile "Panasonic Viera (2010)", the TV sees no video at all. I.e. it lists only the folders, no videos.
• After replacing mpegts with mpeg in the Panasonic sections of the profile, it does list a few videos, namely those with a .mp4 extension. It also correctly shows their duration and screen size.
• None of my *.avi and *.mpg files, let alone DVD VOBs, are listed.
• When trying to play the listed mp4 files, the TV shows a blank screen for a minute or so, then says that it can't play this.
• Debug mode on the serviio server doesn't reveal anything related to these files in the log.

A file that can be listed:

  Code:

Device Spy doesn't see the TV, so I checked on the DLNA web site. The PDF is attached here. Both MPEG program and transport streams should work.

How can I find out what precise parameters are required so that my TV plays the files? Or lists them in the first place?

As your TV doesn't support AVI's (and the Panasonic 2010 profile is for TV's that do) you will need to add this support. Probably the easiest way to do this is to change the inheritance to use the 2011 profile (which implements AVI transcoding) - so change

<Profile id="viera2010" name="Panasonic Viera (2010)" extendsProfileId="viera2011a">
to
<Profile id="viera2010" name="Panasonic Viera (2010)" extendsProfileId="viera2011">

I'm out of my depth a bit here but my guess is that the inability to read or transcode to mpeg-ts files is something to do with mime type mapping. You may get some hints from: viewtopic.php?f=5&t=326&start=70#p2742
Try adding:

  Code:

<MediaFormatProfiles>
   <MediaFormatProfile mime-type="video/vnd.dlna.mpeg-tts">MPEG_TS_JP_T</MediaFormatProfile>         
</MediaFormatProfiles>

to the profile (and try transcoding to a ts).
