Have just installed the Beta of DVDFab v126.96.36.199 and one small problem I found.
Making a backup of a normal DVD5 (main movie) and by defaut DVDFab is putting this as “DVD9” — to begin with I didn’t even notice but only when my media is single layer it then warned me (nice touch btw).
To solve this issue I had to pyhsically select DVD5, and then was fine.
I did try this with another source disc in case this was a glitch but the same thing happened there.
I also checked this back to DVDFab5 (v5.3.0.06Beta and v188.8.131.52) and on both of these it picked up the correct source disc as DVD5
Maybe I’m losing my mind, but I don’t ever recall DVDFab auto-selecting the target size blank based on the source size (especially as recently as v184.108.40.206 or v220.127.116.11).
You sure you didn’t go into common settings and select DVD5 as the default and just forgot you did that?
