I have many problems with the Sony DW-56A that came with my Dell Inspirion D610. I asked Dell to replace it with a NEC. The CSR there did not know if it’s a 6500A or 6650A. I will only know when I receive it.
I read from http://www.videohelp.com/ that the 6500A cannot write to DVD-R DL and DVD-RAM. Although I do not care much of DVD-RAM, I would like to write to DVD-R DL.
In case I get the 6500, is there anything I can do to improve this?
