I have a Pioneer DVD-RW DVR-107D and I use Divx for my Decoder. I have the newest software for the drive and Divx and even downloaded Dr. Divx just to see if it would help. Every player I use says I need a missing plugin but I can't figure out what the problem is. I shouldn't need anything else. I've tried 3 different movies, Pirates of the Carribean: Dead Mans Chest, The Chronicles of Narnia and American Pie: The Naked Mile. They all say that the plugin is missing. Can anyone help me? Preferably a way that doesn't have to buy anything. I'm hoping it doesn't come to that and it's just something I'm not realizing.
