DVDFab Manual for Mac
This window serves as the control panel which manipulates the way DVDFab for Mac works. Note that the default settings apply to most users, which will produce the best results on average. Change the settings at this window upon particular demands, special work environment, or any other given cases, by accessing “DVDFab” icon right next to the Apple logo at the top left corner of the screen, then click “Preferences” from the pop-up menu to bring up this Common Settings window.
Sidenote: The default button at the bottom will switch all the parameters at this window back to factory settings.
