movie maker 2

i have installed movie maker 2 and have had no problems
in creating or editing. when i try to save my movies to
CD i get the error message saying a recordable Cd drive
cannot be detected. I have one inbuilt into my PC and
have tried numerous blank discs but still get the same
message. i have managed to save the films to my hard
drive with no problems. I did copy to a disc using media
player v9.0 but i only got the audio soundtrack and no
video. any help would be appreciated. thanks
