Well i couldn't help but wondering...several times i have backed up my files through Ephpod's backup option...However it never seems to be able to save AAC, WAV formats correctly...always saving it as MP3 no matter what the file type really is. I understand that it can read AAC when the ipod is inserted (as i have updated the software) but still it saves everything under one file type. Of course this means i have to go back and see which files are really AAC from itunes and so on. Is there a way to fix this problem or do i have to switch to another program with this similar capability? Thanks~ :)
