Whats the best freeware to burn data on to a dvd?

I'm currently using nero and I'm not too happy with its performance, whats the best freeware burning software that I can use to burn data on to a DVD? Freeware such as IMAGE BURN (although this one is just for ISOs) so what freeware data DVD burrning software do you recommend? Hopefully basedon actual experience. Please also state why you recommend this software. Thanks
