You can convert 4 at a time using FAVC. The output will be a finished dvd with a simple menu to select which video you want to watch.
http://favcfavc.googlepages.com/ Use the HC encoder that is included, and make sure to install AviSynth and Net 2.0 first if you need them. There are links to both at the FAVC site.
Two alternatives that do the same type of conversion are DVDFlick and AVStoDVD.
