Preserving folder names (mp3 music dvd)

not sure if this is the right forum. i made an mp3 dvd. i have specific folder names with accompanying mp3s. when i used media center edition…some of the folder names were names were not preserved. when i play the dvd in the dvd player…some of the folder names were not preserved. some of the songs would simply be displayed in a list without the folder name that the songs should be in! so why is this? hope i was clear enough. thanks.
