Thank you for everyoneâ€™s help.
But I hope you understand that the reason I am asking is because I donâ€™t know very much (or any). The messages left by Kim Jong and rbrtpl are impossible for me to understand. I am sure they are valuable information to someoneâ€™s ears, but not to me.
Maybe I should post my disc scans here. But before I figure out how to do that, just let me tell you half of my discs received a Quality Score of ZERO, the ones are not zero are also very low.
Kim Jong suggested that â€œforget on-the-fly copying and burn from the HDD instead.â€ I guess he means donâ€™t do disc to disc copying. My computer is not fast either, its AMD Sempron 3000+. So is it fast enough to do disc to disc copying?
My next question is: How am I going to set up two DVD drivers correctly to make burn from the hard-drive optimize?
I donâ€™t know if my PC can automatically set the drivers correctly. Just assume they canâ€™t, then what should I do.
Another important question I still need an answer. Which one of them should be Master? Which one Slave? Do they have to be one master and one slave?
Thank you for your time.
