I built a new system. I put a NEC ND-3550 on the system. Using windows media player, it could not rip a CD that rips fine on my other system. It gets alot of errors and the quality is poor. It is also very slow. I then put a BenQ DW1655 on the system. same problem. I called BenQ tech support - no help. Any help would be appriciated. DVD reading is also poor. Burnig CD's and DVD's is slow and the probablity of getting a good copy is low.
