The Memorex is a LiteOn that has a Memorex label on it. They are the same drives. Even the firmware (when compared at the same revision level) is identical with the exception of the identifier string. And, if you like, you can easily flash back and forth between Memorex and LiteOn firmware versions. The advantage to using LiteOn firmware versions is that they are released more frequently, so if you have some media that doesn't work so well with an older firmware there is a greater chance that you will find a fix in a newly released LiteOn firmware that isn't available in a Memorex version.
