Presently I'm using Nero 5.5 and have had no problems: however I have compressed some of my music in mp3 format and everything went find during the burning, but now I am unable to play the cd on my computer. I do not have an mp3 player as of yet, and if I am reading correctly it states that Nero will not play cd's in mp3 format only on windows 95-98 and NT.I am no expert in this but has anyone had this problem or am I just not up to par with this software.Thanks
