Transcoding only multichannel dsf files

[Veganfloyd]

Thank you very much, Simon. I understand that this is more of a me-problem with ffmpeg than anything else, and I do appreciate the follow up.

Unfortunately, I am getting an error message: 'convOut' option incorrect for converter; correct highlighted value and retry. I googled around, found your advice on installing ffmpeg from the SynoCommunity, did so, restarted MinimServer, but to no avail.
