Raw Video files not visible on samsung telly

I have been using serviio for some time (fantastic product!) and have always found answers on the forums. However, in this case I have spent quite some time trawling the boards and have not been able to find the answer to my issue.

I am running serviio 1.4.1.2 on ubuntu 14.04 successfully, but somehow I am not able to get raw digital video .dv to be viewed on my samsung 55C6000 telly. The raw dv files were uploaded using dvgrab and are simple home videos. On the telly when i browse to the videos folder i am not able to see any .dv files.

The serviio.log file run in debug mode does not detect the .dv files, there is no record of them in the detailed log file. Other files (.avi, MTS) I am able to view and play without any problems in the same directory as the dv files, so it is not a connection issue between the telly and serviio. ffmpeg is installed and appears to be working OK :

The debug log indicates that it is using the profile for Samsung TV / player (C/D-series).
Attached is a debug file, with me browsing to the /Videos folder from the telly (fixed IP .87)

If anyone can help I would greatly appreciate it - the kids are driving me nuts to see the home videos on the big telly in the living room
