I have a new HP laptop. It has Windows XP. I am making a sliceshow in Powerpoint and am having trouble with my music playing. I can import tunes from itunes but some will play and others will not. I am converting the music from AAC to MP3. I have looked everywhere I can think of. The only thing I noticed that looked funny was when I clicked on the picture in powerpoint under sound settings it had length of song set as 0:00. In itunes it shows the proper length of song. Any help would be appreciated. Oh, by the way, the song is on a cd I purchased then imported to itunes. Thanks!!
