What is a really good wmv and avi to dvd converter?

hello,
i have many movies in avi format and some small clips in wmv format which i would like to convert to dvd format.

can anyone please comment on what is a really good converter i can get for free? thanks a bunch

Also, can you guys also tell me what are the best dvd formats that are supported by nero and or nero express?
thank you

Doesn't dvd burning software support most formats? I thought it did.....you should be able to burn either of those to a DVD. But, I could be wrong, I suppose.

Best one I've found is MediaCoder, just run a Google search for it. It's free, but it's not the easiest program to use.
