I have a Dell Inspiron 6000 Laptop and I have a Sony DW D56A DVD RW drive. I can’t burn anything but coasters. After the burning which I use DVD FAB and DVD Shrink for, I put the DVD Backup into my dvd player, it goes to play and then it stops. I push play again and the screen goes to play and then boom, stop again. I have changed the firmware to sony’s latest, i.e. PFS3 but to no avail, any help?
