I just read the page but Im too confuse to try it. Actually my superdrive writes at DVD-R > 1X CD-R > 16X CD-RW > 4X The speed of the CD-R burning is wonderfull, but the speed of DVD-R is to bad. I really appreciate if someone can share his/her experienced about doing this firmware upgrade with more detail. My Superdrive MATSHITA Revision - DWDB ID prod - DVD-R UJ 815
