what software to use???

Hi,i would like to know what software i should use to convert and burn my avi movie files in to DVD format,what is the best software? i used Nerovision but i didn’t like it much on a plus side i could put 2 movies into single DVD-R i’m looking for the simillar software that i can use that can fit 2 movies on single DVD-R.

http://www.videohelp.com/ I use VSO ConvertXtoDVD is not the best but is fast. The new Cucusoft is not bad but the speed is a big issue for me.

DVD Santa very good for avi files.
