I have a 6650 burner and use TDK +R media. Burns all fine at 8x speed. Now I have ‘upgraded’ to a 6750 and it burns the SAME disk only at 6. I thought crappy drive and bought now a 7551 with the same result. They only burn the same disk at 6x speed!!!
I tried Original FW, Liggy FW and modified FW all with the same result: 6x speed.
Is there anything NEC changed with those newer drives? Why would anyone want a newer drive to burn SLOWER? I now use the ‘older’ 6650 to burn 8x speed DVDs.
Any help, perhaps some new FW coming up soon? Anyone else had this experience and solved it?
