I have a LG 4521B Combo Drive and used to work fine until now.
Today I upgraded my Mother Board (I think it has nothing to do with it) and upgraded my windows to WinXP SP2 (Media Center Edition). I can read CDs but not DVDs. Everytime I put a DVD in the led flashes for a while but I can't see any content in my explorer in the dvd.
Any idea what could be wrong.
