I'm just wondering if I am having the same problem or not.
I have been running serviio excellently through my Synology DS212j NAS and it's worked really well to a Samsung TV.
Recently I bizarrely managed to delete all my videos and so set about rebuilding my collection (if you want to know how I deleted my videos, that's at the end). I also updated the serviio package on the DSM and reinstalled/updated Java on the NAS.
I can also see series fine, but not movies. However, I'm not sure it's just a metadata problem because my log file contains a lot of this:
2013-10-05 13:03:04,646 WARN [LibraryManager] Skipping processing metadata for an unsupported file. Message: Unknown video file type.
2013-10-05 13:08:05,883 WARN [LibraryManager] Skipping processing metadata for an unsupported file. Message: Unknown video codec.

2013-10-05 13:13:07,660 WARN [LibraryManager] Skipping processing metadata for an unsupported file. Message: Unknown video file type.
I can see the movies if I go into Folder view on my TV. I can also play them fine from the folder view on my TV.
However, I cannot see them under the normal Movies view at all - not as file names, nor as movie names.
Is this the same problem as chrisy1972, or is this two problems (metadata and transcoder)? I have attached a log file from the server instance of serviio.

[How I deleted my videos]
I was doing a bit of a spring clean of my Synology Diskstation 212j. I store my video files under volume1/homes/serviio/Video and always have done. I deleted some other folders I created when I had initially set up my NAS, such as volume1/video and volume1/videos, but deleting those (empty) folders deleted the videos within the serviio/Video folder. Very odd.
