You need a very large harddrive... all the files to be burned to a CD, for playing on a regular music CD player, must be WAV files.
You will need a program that converts MP3's to WAV's. I use Goldwave (www.goldwave.com) with the LAME converter.

"Windows ME, Windows 2000, or Windows XP is required for version 5. Windows 98 works, but is not officially supported. Windows NT/95 are not supported and will not work (please download v4.26 instead)." And there is a link for the 4.26.
You can also record from LP's. Get a cable with RCA plugs on one end, down to a 1/8" stereo plug on the other, plugged from your line out on the stereo to the line in on your sound card. You can record the LP. In Goldwave, you can then process the WAV, reducing, or even eliminating pops and clicks. Then burn to CD. A great way to archive those old collectable LP's by esoteric artists that will never be available on CD.
