Ts-l633p dvd+rdl write error




I´m trying to write a double layer Dvd with all my pics but the Toshiba disc creator send me an Writing Error, then i try doing with alcohol 120 and sends writing error too (Lenght 16)

The file size i want to store in the dvd is 7.1 gb.
The recordable double layer Dvd i´m using is a Memorex DVD+RDL 8x and 8.5 gb.
The laptop is a Satellite A305 S6905
The DVD device is TS L633P

The OS is Windows Vista home premium spk1

Wen i buy the laptop the specification says it can burn double layer dvd´s,

I´m try several programs to try burning the double layer dvd and all sends error mesages.

Any ideas what´s goin wrong with DVD Burner?
