I made a dual layer mp3 dvd (7.96 GB) and figured it would work fine on my DVA 9861. But only the first 70 folders show up on my head unit. All of the folders show up on my home Sony DVD player and the songs play as expected. My 9861 has played many dual layer movies off of DVDs I own. Is the Alpine DVA 9861 not compatible with dual layer mp3 DVDs? Could my problem be related to settings when creating the disc?
