Try this firmware update for your burner to see if it works. The problem seems to be that the media you're using is too new for your burner (notice that the firmware update is almost 5 years old). Use SIW to check if your laptop has USB 2.0 support, and if it does, you could get an external non-slim burner for it.
Alternatively, you could try finding Taiyo Yuden 8x (TYG02 dye) DVD-R blanks that it probably does support.
