I recently built another computer. I use Windows 7 64 bit. I purchased an ASUS CVD burner that came Nero 9 software. I am used to using Nero 7 and have burned several mp3 CD's and DVD's with it. However, when I tried to do that with Nero 9 I was informed that I needed to purchase a plug-in called Grace-note, which I did. However, I still cannot burn mp3 DVD's. Does anybody know why I am having trouble with mp3 files all of a sudden? Mystery... Thanks for reading and thanks for any information you may have....Jim
