Many of the tools we have are actually freebies available on the web...things like DVD Identifier, Nero DiscSpeed, ImgBurn, etc. etc.
Why do we need other programs if DVDFab does the job?
Just look at the various threads...all problems...extra tools can sometimes do the job better... not to take away from DVDFab...It comes with the VSO burner built in, and I personally have never had a problem with it, yet I keep Imgburn in my toolbox, just in case...
Do you drive?
Do you keep a spare tire in your trunk?
If so, why, when the 4 installed do the job?
Have a tire iron there, too?
Not needed to drive the car or put gas in it... (or pay the mechanic to fix it...).
