Until now I used a Liteon drive, which mostly made not very good quality DVD's.
Kprobe PI around 300, PIF around 30.
Now I use the 3520A and almost all of my DVD's are coasters, PI around 500, PIF around 40, but Nero DVD speed always bad at the end.
I used RICOH JPN R02, YUDEN 000 T02, RITEK R02
And then, I wonder, sometimes I get a good DVD with PIF below 100, PI below 3.
What can be the problem?
I changed from secondary master to primary master, which makes no difference.
I have no ad/spy-ware or antivirus running while burning.
