Best Free Alternative to Nero CD DVD burner

Nero 8 is probably the best piece of software available in the market for CD/DVD Burning Purposes, but it is expensive and comes with a lot of feautures you are never going to use.
On the other hand CDBurnerXP is a free application to burn CDs and DVDs, including Blu-Ray and HD-DVDs. It also includes the feature to burn and create ISOs, as well as a multilanguage interface. Everyone, even companies, can use it for free. It does not include adware or similar malicious components.

Key Features

• burn all kinds of discs
• audio-CDs with or without gaps between tracks
• burn and create ISO files
• data verification after burning process
• create bootable discs
• bin/nrg → ISO converter, simple cover printing and much more!

Nevertheless to say, I have been using it for almost two years and I have never had the urge to go and buy Nero or other expensive similar software.
