I have Nero 5 and lately i have taken up burning audiobooks in mp3 format. I have carefully numbered each track in the file (ie)agatha christie ch 01 agatha christie ch 02 and so on... I wanted to make sure they would burn in order of chapter. On one disc i burned quite a few audio books and every single one of them plays chapter 02 first and puts chapter one at the end of the file so u hear all the other chapters before u hear the first one (eventhough they were correct in the compilation). I have done every thing and burned a tone of discs as i played around with the file names and still my mp3 player wont read them in proper order.GGGGRRR.... does it have to do with the ISO name? and if so, what is the standard way to number,or structure the file directory, so the files are read in the order inwhich they were intended. I thank all who reply with help!
