I also have same problem. My DVD is Pioneer A06 and framware is 1.07. The burnning software is Nero 6.0.30 and DVD X Copy Express. When I burn the movie, such as S.W.A.T and Finding Nemo, to Verbatim DVD+R (1x-4X) disc, it does not work. Neither DVD player and Pioneer A06 can read the files and play the movies. But when I change to another disc (TDK DVD-R 1-2x), the is no problem at all. That is so strange.
