Thanks very much @jadburner, I will post more results. I'm not a professional in analysis, for quality check nero dvd cd speedy is better ?

I wouldn't say it's better, but CD-DVD Speed is more widely used and has a longer track record. It is only useful for CDs and DVDs, however. For Blu-rays you would need Opti Drive Control or VinPower Tools.
