CD/DVD burner XP4 : freeware

Despite its name, CDBurnerXP is not just a CD burning application for Windows XP. It's actually one of the most full featured free CD and DVD burning utilities you're likely to find for Windows 2000/XP/Vista.

CDBurnerXP 4 was recently released, and it has some impressive new features:

• Support for burning Blu-Ray, HD-DVD, and Double layer DVDs
• Support for FLAC audio files
• Disc to Disc copy for audio and data
  
• Save discs and compilations as ISO files
• Support for WPL playlists

While Windows XP and Vista include some basic CD and DVD authoring features, CDBurnerXP is about as full-featured as many commercial applications out there. And it's free. The program is donateware, so if you want to download the latest beta versions you'll need to make a contribution.
