It may be that the source DVD is using some compression method to
fit the content on a 4.7G DVD.  The size of the original DVD can
be checked with "dvd+rw-mediainfo" (sysutils/dvd+rw-tools), ex:

	# dvd+rw-mediainfo /dev/cd0

If the source DVD is a 4.7G DVD then the simplest way might be to
first make a duplicate image with "dd", for example:

	# dd bs=2048 if=/dev/cd0 of=duplicate.iso

This should produce an image of suitable size in the current
directory to fit on another DVD which can be burned with
"growisofs" (sysutils/dvd +rw-tools):

	# growisofs -dvd-compat -speed=4 -Z /dev/cd0=duplicate.iso

The preceeding commands are only examples and may need to be
adjusted for your hardware/situation.  

HTH,

Randy
