Why does the media player keep showing "new wave sound" in the playlist?

ok i got a camcorder dvd rw and i finalized it. then i put it in my CD writer/DVD ROM and i went to media player and it only says “new wave sound”. i have been wasting 2 days on it trying to figure out whats the problem.

maybe it could be that i need a CD RW/DVD - Rom or something other and maybe i need to install it in my cpu. but i dont know if it might work or not.

can some1 tell me why does the media player keep showing “new wave sound” in the playlist?
