I was wondering why I just bought some Sony DVd+R 1 x 16 speed 4.7 disks and my Sony burner won't aknowledge them. These are the same type of disks I've used for ages with my recently updated Nero program. I tried DVD info and DVD Identifier and didn't see these on the lists. I notice different media numbers tho. So not sure whats going on....I appreciate help with understanding whats up.
