I have Channels server installed on raspberry pi machine that connects to the personal media files and the DVR files on a Synology NAS via NFS.
This has worked very well until added the movie trailers for each movie. As a workaround, I have the users group permission set to read/write. If I change the users group permissions to read, I do not get the trailers.
I have seen the problem resolved if Synology is running DSM 7, but I am stuck on DSM 6.
