I am adding songs to my slideshow. One day I heard them, the next day not. When I go to the sound icon, everything is working. They are MP3 files. I am too afraid to download anything free on my computer because you always get tag along **** that attaches itself onto your computer. I have already converted MP4 from itunes to mp3, which did not work in DVD maker, so I went to Movie Maker. Are you serious---another conversion to WMV is necessary? Isn't there an easier workaround. I have software I can't even use with normal music. Most music is Mp3. Why create something that won't play that!!!! Frustrated.
