Since I have been using open source on my personal laptop I found myself using CDBurnerXP more and more to burn my CD's and DVD's.
I was using the software that came pre-installed (Sonic) but I found that this neat tool was better, and didn't crash as much as Sonic did.
The software can be downloaded from: http://cdburnerxp.se and it is only a 3mb install file, so it is quite a small utility too.
The beauty of it is that you can create as well as burn ISO images, convert nrg and bin files and do much more. I would recommend going to the site and having a look for yourself and downloading it.
Recently I have discovered that its license even enable you to use it within your business.
