    You mean a hardware CD/DVD reader?

    How it can detect the difference?

    I guess the laser reads the inner parts of the CV/DVD
    to identify if it is a DVD or CD. That is not that difficult to
    do I guess. The readers can read out from the CD/DVD the
    manufacturer and I guess there's some info about type as well.

    As one of mobile devices fans, I was looking for a valuable all-in-one converter that not only can rip DVD and convert video, but also backup my ipod files to my computer. Recently my friend recommend me the Best DVD Converter Suite
