I am using 32-bit CDBurnerXP 4.52 on a 64-bit Windows 8.0 laptop and am trying to make a copy of a movie DVD (that I bought) for backup purposes. However the instructions on how to do so seem confusing and ambiguous to me, unfortunately.
I chose "Copy or grab disc" and selected "Hard disk" in order to create an ISO image file.
What I am puzzled about is, that the resulting image file of this 94 min long movie, which CD BurnerXP created, is some 8 GBs in size. For all I can tell, it is a regular movie which should result in an image file of less than 4.7 GB.
So what is happenning here and why?
