nxdoom problem..

Hi, ive burnt a few cd's of nxdoom latley and its not that they're burnt incorrectly, i get to the modlist menu and choose what doom mod or game i want to play and it loads the wad but once its done loading it just black screens before dooms main menu, it only happens on the ones i have the xm music wads for, plutonia and tnt start up and run fine and they are the only two on my disk that dont have music wads.... anyone have any idear why this would happen?

How did you create the XM wads, or did you get them from elsewhere?

I want to know too
