Well, this indicates that this Ez Dub software makes use of the NerÃ¼ burning engine. I had seen a Version of NerÃ¶9 on that Liteon website, no idea if this can be used also.
Additional thoughts: Ez Dub software is not required at all to operate this drive. The only thing you need is some functional CD/DVD burning software.
And if you really want that Ez Dub stuff, you should try the disc that came with the drive - but caution, Nero7 is not declared as Windows 7 compatible.
