I have a individual machine. I bought this machine this month. The install is very better. I set up lots of software. I have also set up Nero to burn the CD. I only learned of the machine. I do not recognize much about software. But I try to learn this. I want to ask something like DVD recording speed. Today I was spelling a DVD then I was writing very dumb. So I recognize I can alter the recording speed of built in DVD burner.
