I have a dvd-video (pressed) disc that my GSA-4120B can’t recognize (I can neither play it nor see it in Explorer) on my winxp-sp1 machine. That dvd-video can be played normally with my 3-yr-old dvd player and on another PC with a dvd-rom drive GDR8162B (LG OEM, I think).
I didn’t expect this kind of incompatibility. Anyone here has the same problem? Or, is my drive not working properly? Please help.
