Hi Vinh,
Sorry, I haven't replied, I've been testing it myself.
I've tried using Telbook versions 1.0, 1.1 and 2.0 but I can't get the .bin file to be read on my MPx player. It either comes up as "no file" or "file error". Are you getting these messages too?
Where did you get your TelBook program? Mine's came from the original cd with the player, but that doesn't even work.
I will try to find out some more from mp3 manufacturers and see what I can get from them.
