I am NOT CERTAIN about this but I an mot sure that the CDDB that can be downloaded to the Brennan is still being updated (by the people who created it)
If you want to be sure you have the latest version the B2 Menu command to download it is.
or from the Maintenance Menu section (direct web download)
I think that as you Rip a CD the Brennan may also try and access some other databases for you if you are on line.
