DVD folders wont display in Apline IVA-w200

I’ve been burning music to my DVD’s to play in my Alpine player. The music plays and sounds great. However, when burning my DVD’s, I create a folder structure which divides the music as follows:

Music DVD



—individual albums

I’ve been using NERO to burn the dvd’s. When I put the DVD’s into my iva-w200, the list of folders only shows the names of the albums. I can’t browse individual folders by genre or artist. Again, all the music on the dvd is accessible, I just can’t do a breakout based on the upper levels of my folder structure. It seems only those folders which directly contain mp3 files get shown.

Is it something in my burning process settings that I need to change? Any ideas or information would be appreciated, this one’s been nagging me for a long time.
