My Compaq DVD-ROM DVD-115 is refusing to read commercial dvd’s, being of whatever region. It can read with ease data dvd’s and home-movies dvd’s as long as they do not have any kind of encryption. It is not a question of codecs since the second dvd drive, being a Pioneer dvd-RW 107D, reads them (css-encrypted commercial dvd’s) with ease. Can someone please shed some light on this problem? How can I get my Compaq dvd drive to read commercial (css encrypted) dvd’s?
