Audio CD in DVDRegionFree +CSS

Can any one tell me what is thw function of the audio cd box in Regionfree? There is no explanation in the help files. What do I lose if I uncheck the box? I was told to do this to resolve a problem in Nero 7.

I am just guessing as I use Plantinum, but some players use to require an Audio_TS folder even though that folder is empty. This may allow you to choose to have this folder. Click on ? in upper right coner were - & X are placed and you might find your answer. I have DVDidle Pro which includes same functions but have never used it because Platinum worked so well. I have heard Nero 7 has some bugs and there may be an update to fix them.
