I am trying to copy a .wav file onto a CD from Media Center. It will not recognize that I have put a CD into the drive. I have similar problems when I try to use Real Player. Real Player will tell me that the file will not fit. ( file is 400mb going on a 700 mb disc). If I use Windows Explorer I can copy the file onto the CD but the CD will only play on a computer and not in a music CD player. I have a one year old Dell E310. I had no problems making audio CD's with my old 4100 series using a different CD burner program which I no longer have. Do I need to change a setting somewhere or do I need a different program. Lost!!!!
