I have successfully burned many Memorex 2.4X DL discs using my Lite On SHW 160P6S burner and Nero Burning ROM 7. My burner firmware is version PS0B. I recently purchased Memorex 8X DL and tried to burn a disc. It wouldn't work. I got an error message saying that the burn failed. (No reason given.) So, I went to the Lite ON website and flashed the latest firmware version (PS0C)for my burner and tried again. I still can't burn the 8X media, however, I am able to burn the 2.4X Memorex. Does anyone know why this is happening? Is it because the latest firmware does not cater to Memorex 8X DL media? Thanks for any help.
