i bought this burner and worked fine for a month....now it does what it wants.....doesn't open sometimes then opens a little, spits out fast, opens half way then closes then opens all the way and stays out...i think u get it. anyway the last movie i did was mr 3000. i had this problem with the last burner so i took it back now again could it be 2 bad burners or is there something i am missing Peace
