Most people consider Nero as the most efficient burning software. If you only use Nero for burning and don't usually the full Nero Suite then what you need is Nero 10 Free version. Unlike a trial version this won't ask to you to purchase the full version and won't have a trial period.

This free version only has basic burning options such as Data CD, Data DVD, Copy CD, Copy DVD and Image Burning and Creation. You can download it from here.
