Or.. here's another idea, which might be feasible.

You could just ignore Jemplode, and use a recursive FTP client (eg. wget or ncftp on Linux (there might be something similar on Windows) to just grab the entire /empeg/fids/ heirarchy from the player.

Then run a script afterwards to rename the files from hex to something meaningful (artist, album, title, etc..) from the associated tag files. (I think there's already a script that does that, somewhere, but again.. trivial on Linux).

And finally another (or the same) script to copy the empeg tag information back into the ID3v1/v2 embedded tags. This should also be a simple script on Linux, doing callouts to mp3tool to modify the files.

If you were doing it on Linux, I could even save you some effort, and quickly cobble up a bash/awk script to do all of that.

Cheers
