I have been able to follow all the directions, but when it comes to changing the setting to DVD-ROM, my drive (HP dvd840) is not listed. I keep getting 'Failed' Reason: Invalid Command Operation Code' Could someone please help me with this; without having to purchase a new drive? I have tried using ImgBurn, but it freezes on me. I have been able to use dvd decrypter, but am not able to find where i change the setting to DVD-ROM. I have tried one disc, but my xbox wouldn't read it; set as dvd and not dvd-rom.
