I have been using ExpressBurn from NCD. Its free. This is the link to the page where you can download the software.

Express Burn Disc Burning Software
Burn Audio CDs and Data CDs, DVDs or Blu-ray Discs
Free CD burning software to create and record audio and data CDs on Windows or Mac.
Burn audio, video or files to CD, DVD or Blu-Ray
Drag and drop files straight into the application
Super fast burning to save you time
Record data or audio discs quickly and easily by dragging the files you want onto the icon and clicking Burn CD. The software then does the rest, including converting the files if required. Express Burn is also the fastest CD/DVD writing program in the world using proprietary optimizing systems. But don't believe us, try it for yourself.
You have to understand the type of media you are recording to. I didn't when I started and I wasted a lot of disks.
Another source I check when I need new software is CNET.com. They have thousands of free downloads and its a very reputable site.
