Audiobook problems: Clip Jam database technical details?

Thanks very much for your input.

Try to carefully curate the ID3 tags of the mp3 files (v2.3, delete v2.1). Need to display unique specificity within first 12 characters of “Album” and “Title” fields. Use 2-digit track numbering (00-99).  Maybe limit the total number of audio files to less than 1500 ??

Have you determined whether using other tags in the metadata beyond Album and Title will affect the database size?

I read on this forum that these devices prefer ID3v.2.3 ISO-8859-1. I looked and all the audiobooks my wife has are v.2.3 UTF-16. Do know if that can create issues?

Thanks again for your help. Much appreciated.
