Disc Messenger, as an important notification feature, appears in DVDFab since ver. and onward. Its designated function is to timely notify users the newly supported Blu-ray and 4K Ultra HD Blu-ray discs containing new protections, which DVDFab was not able to decrypt at the time when users first tried. 


The notification can be sent in two ways (see the pic below), via a popup inside DVDFab program, or via email of user's registered account (exclusive to the 365 subscribers). 



Tip: It's not necessary to try repeatedly on an unsupported disc due to new protections, it generally will be supported in 1~3 days. But to save your time, it is suggested that you run your 2nd try until you receive our official notification.
