I use DVDFab Platinum 220.127.116.11
After I burn a DVD, I get the message "Process Failed". However the burn is just fine. This just started recently after using DVDFab for a couple of years.
Try using Imgburn instead of the VSO burn engine. Here is a video from YouTube courtesy of Troy on how to configure ImgBurn to work with dvdfab http://www.youtube.com/user/dvdfabtroy?gl=CA&hl=en
