Actually there's no problem at all with your PC suite. You only have to configure it properly. 1st go to options then settings. Go to "Location of My Collection" and browse the folder you want your m4a to be saved. After that, go to "Conversion" tab and choose m4a/48kbps (cool!) and "Convert automatically" . After this, scan the mp3, wma, etc.. and then convert on the "File" option. The m4a songs that you have converted will go to the folder you selected or browsed on the "Location of My Collection".. Hope this helps. I have a 512mb ext mem and have around 350 m4a songs for this. Cool!
