I’m making a video from a trip I took. I’m adding music with parts of the video. I’m sure the file is getting pretty large especially with WAV format music. If I use MP3 music, or MP4 music that will save room, which I assume helps fit the file on a DVD. Is it possible that MP3 music will not play on a regular DVD player? Addressing your last question. Why would one want to make DVD with just audio clips? Couldn’t those only be played on a DVD player?
