-g- im such a dumbass -_-
when i tried it, the dvd drive seemed to lock itself (green light on, didnt open the tray)
after reading your post, i gave it another shot and it works...
i guess it was human failure... i probably didn't put the dvd on a perfect position on the tray ( and im carefull with that... i always put it inside gently no pun intended )... so it acted stupid
thanks for the help chef
