Hi I have a laptop with a toshiba sd r6372 dvd writer in it. When I try and burn a dvd film onto disc with either nero 6, dvdecrypter or clone dvd it seems to write successfully but when I put it back into the toshiba drive the light on the tray stays on and the disc is unreadable(Not recognised?) 2 of my home dvd players wont read the disc they just spit it out as a disc read error? I have made sure the finalize box is checked in nero. It will burn a music cd fine with no errors and it will re access it. I have upgraded the firmware can anyone help?
