I always found that Xilisoft software a bit buggy, usually the video was out of sync with the sound.
You could try using a trial copy of Adobe Premiere Elements, Cyberlink PowerProducer or Ulead MovieFactory.
One of those might let you do a one of DVD burn.
Also tryout Nero , I think it has a module for DVD movie burning that will convert your divx files to a normal DVD format.
