Glad you are up and running now. The PS4's message that you see is their message (not Mezzmo's) so we cannot control that.

When you maintain your library, it will not pre-transcode your files. Maintain library is for finding & adding new files, collecting metadata for files, and removing non-existent files.

If you want to prepare files that have not yet been pretranscoded in your whole library or in a folder or in a playlist for your PS4, then you can use the Pre-transcode features. See this wiki topic how to pre-transcode only those files that require pre-transcoding for your selected device - http://www.mezzmo.com/wiki/doku.php?...nscoding_files.
