DMR-PWT520 help me figure out what profile to use/create

Hi - I'm hoping you can help me with a some information and advice. I've got a Panasonic DMR-PWT520 and I'm running Serviio on a Synology DS212j. I'll say upfront that I have read any other thread that looks vaguely relevant, especially the 1 or 2 others that are related to this specific device, but as the problems being experienced and the results of experimentation don't seem to correlate with my own, I thought I should start a separate thread.

As you can see I've done some experimentation with different renderer profiles and file formats. All the files mentioned were created from the original MKV file which has h264 video and DTS audio. I would like to try the new profiles that have been created for Panasonic, but unfortunately I'm not proficient enough with unix to find and edit profiles.xml. I do have a friend who's offered to help me try to do that though, hopefully soon.

For now and with the help of you good people I'm hoping to just deduce a bit of what is going on and also It would help my analysis if I could know what each of the renderer profiles that I've tried so far is configured to do (I can't find that information anywhere). If possible maybe someone can recommend another renderer profile to try.

The most successful profile so far has been the Sony Bravia 2012 profile. Everything plays, however letter box format films are in the wrong aspect ratio - either stretched vertically to fill the whole screen, or retain the right shape but positioned all the way to the top of the screen (this file is an example of the latter).

Here is a summary of how each file has played on each profile.
Panasonic 2010:
MKV (DTS or DD)– does not play
MKV named MP4 (DTS)– does not play
MP4 named MP4 (DTS) – does not play
MP4 named M4V (DTS) – does not play
MP4 named M4V (DD) – does not play
MP4 named MP4 (DD) – does not play

Panasonic 2011:
MKV (DTS or DD)– does not play
MKV named MP4 (DTS)– does not play
MP4 named MP4 (DTS) – does not play
MP4 named M4V (DTS) – does not play
MP4 named M4V (DD) – does not play
MP4 named MP4 (DD) – does not play

Panasonic 2012:
MKV (DTS or DD)– does not play
MKV named MP4 (DTS)– does not play
MP4 named MP4 (DTS) – does not play
MP4 named M4V (DTS) – does not play
MP4 named M4V (DD) – does not play
MP4 named MP4 (DD) – does not play


Generic DLNA Profile:
MKV (DTS or DD)– does not play
MKV named MP4 (DTS)– does not play
MP4 named MP4 (DTS) – does not play
MP4 named M4V (DTS) – does not play
MP4 named M4V (DD) – Plays, aspect ratio OK, but no audio
MP4 named MP4 (DD) – Plays, aspect ratio OK, but no audio


Sony Bravia 2012:
MKV (DTS or DD)– Plays but letterbox films have wrong aspect ratio
MKV named MP4 (DTS)– Plays but letterbox films have wrong aspect ratio
MP4 named MP4 (DTS) – does not play
MP4 named M4V (DTS) – does not play
MP4 named M4V (DD) – Plays, aspect ratio OK, but no audio
MP4 named MP4 (DD) – Plays, aspect ratio OK, but no audio
