the problem is that the wave is drawn on the plane called default_theme_BG which also contains the little dds "wallpaper" and i have been unable to separate these 2
i can draw the dds image over the wallpaper but that is of no use if the wave doesn't move with it and until i figure out how to remove the dds itself (you can't make it transparent and removing it will crash the ps3)

edit:

on a side note, i decided to release the tool that allows access to the wave configurations i quoted above,
you can find it from My site
