I have my eyes on a LiteOn LTR-52246S drive. Could someone help me with the disadvantages, if any, of the drive, how well it would work with SafeDisc 2.9, and how I would make a SafeDisc 2.9 disc with it? Also, I have seen that this is a 2-sheep burner. Is this true? If so, $40 is quite a good price.
