I have a question,
if I want to copy a full DVD9 witn no compression,
I choose fulldisc mode with DVD9,
I wonder if even choosing DVD9 option in fulldisc there are some kind of compression,
because I have noticed dvdfab change the size of some vob files,
if doesnt change the size of the total DVD9 but it changes the structure inside the DVD
so the question is, choosing fulldisc DVD9 there are some compression or is just a exact copy backup of the DVD ?
Thanks in advance.
