Fastest AVI to DVD encoding?



I am wondering about the fastest AVI to DVD encoding approach. So far I have tried VSO ConvertXtodvd 3 which was pretty slow (and then burnt the project with Nero), Nero Vision 8 with direct burning which was not bad, and as I am typing this I am using Roxio MyDVD 9 which seems glacial.

What is the fastest package/approach for avi to dvd encoding?
Are there any settings that help speed things up?
