easiest way to backup home made DVD

[yonas abraham]

Hi,
I usually edit videos and make DVD.  what I want is an easy way to 
duplicate (create a backup of them) as the DVD-R are very sensitive to 
scratches. Upto late FC4 I used to use dvdbackup using the following 
three steps

dvdbackup -M -i $dvdsource -o $tmpdir/ -n $title
mkisofs -dvd-video -V $title -v -o $tmpdir/$title.iso tmpdir/$title
growisofs -dvd-compat -Z $dvddest=$tmpdir/$title.iso

But as of lately, I can't compile the dvdbackup from source as most of 
the binary I found them are broken.

I look for an alternative and found some like (k9copy, dvd9to5.pl, 
DVD::rip and so on). But I found these packages an overkill to my 
project as I don't need to "shirk" or transcode. Plus I don't have an 
encrypted DVD.

is there an easy was to duplicate 4.7GB, unencrypted home made DVD's easly?

thanks

BTW, I am using FC5.
