the file extension that the visualizations use are specific to windows media player. they will not be read by your dvd player or ps2 or whatever you intended to use. you could try and google for a program to convert the files to mpeg or avi format, then use a movie maker (windows comes packaged with one for free) to add the music in. it will not however necasserily be in sync with the music as the visualizations move with the music. if you used the movie maker all you would be doing is adding audio to a static video. close as i can get in my 2 minutes of thinking though
