supported read features are: cd-r,cd-rw,cd multiread,cd method 2, dvd-r,dvd-r dl,dvd-rw, dvd+r,dvd+r dl,dvd+rw, dvd-rom. thanks for the help by the way. this has got me stumped and frustrated. these are store bought dvd's by the way. some i assume are dl. I use them on my other computer and the ones that have 4 gigs and less play fine, but not the bigger sizes.
