What is going on with my LiteOn LH-18a1p

Im trying to burns some discs and when i put my Ritek discs in my drive makes this clicky click sound and sits like a knot on a log. It will take my cheapy HP CD-Rs but not these and ence i cant burn DL with this drive. I flashed reflashed this drive with the BenQ DW1800 FW and LiteOn GLOJ FW and it seems to make no difference what can i do to get this fixed or do i need to bang down liteons doors for help?
