What is NeroMix?

Please excuse me but I am new to the Nero 6.6 suite. I have an oem license for Nero bundled with my Liteon burner. I have installed everything except InCd and NeroMix from the update page. Is NeroMix part of my oem package? What does it do?.. I am a long time Nero 4, 5.0 and 5.5 user so please bear with me. Thank you.
