Whatever software you use for burning should have an option for burning as a DVD. Nero does a good job of this, I'd recommend it. If not, then you can just burn a DVD with two folders in it. One called AUDIO_TS and one called VIDEO_TS. Usually nothing goes in the AUDIO_TS folder, but it should be there just for proper DVD structure. There should be some .BUP, .IFO, and .VOB files to be put in the VIDEO_TS folder that you get from converting.
I use WinAVI, it works great and is very simple. It can also burn your converted files. Free trial here:
