Ok, i did this before & got all the files on there. A few weeks ago, I burned 4 MP3 files onto a 700 MB CD. The MP3's together = 328 MB. But for the life of me I can't do it again. It's just a recording of 4 sermons that we did at church. The cd says not enough room. It's 328 MB of data (about 5 hours of sermons). If I'm not mistaken, 328 is less than 700. I even mereged all the MP3's so they are 1 large 328 MB file. So I'm stuck. I've tried Nero, windows media player, windows xp pro, Acid pro, wavepad ...... I'm stuck. I want these because I don't want to have to burn 4 cd's everytime someone want's to listen to our church's revival.. Any help would be much appreciated.
