As pinto2 pointed out, the program is known for the frequent addition of third party applications so this could be some new implementation here.
Interestingly, the supporters on DVDInfo Pro plaster their product across several forums but refuse to provide support in these forums. According to them, the forums are used only for news releases.

DVDInfo Pro support can be found on the DVDInfoMantis site.
Oddly, there is no reference in the programs help files to this site.
