EDIT: dvd95, k9copy and dvd shrink all perform pretty much the same task.
dvd95 explanation can be found on its homepage
k9copy explanation can be found here
DVDShrink explanation can be found here
ALL OF THESE APPLICATIONS ARE USED TO CONVERT DVDS TO FIT TO A 4.7GB DVD
EDIT 2:
I was able to get dvd95 to install into Ubuntu 15.04.
For dvd95 and Ubuntu 15.04 install, add the following lines to /etc/apt/sources.list
deb http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty universe
deb http://us.archive.ubuntu.com/ubuntu/ trusty main
then run
sudo apt-get update
then run
sudo apt-get install dvd95
After dvd95 is installed, remove the lines above or comment them out like below:
# deb http://us.archive.ubuntu.com/ubuntu/ trusty multiverse
# deb http://us.archive.ubuntu.com/ubuntu/ trusty universe
# deb http://us.archive.ubuntu.com/ubuntu/ trusty main
then run
sudo apt-get update
so the repositories go back to normal so that you don't mess up updates in the future.
K9COPY:
I was able to get k9copy to install into Ubuntu 15.04. It is the closet thing I can think of to dvd95.
I installed it by first downloading the .deb file from here. I downloaded thek9copy_3.0.3-1_vivid_amd64.deb version. Then I tried the install by typing in from the downloaded file location:
sudo dpkg -i k9copy_3.0.3-1_vivid_amd64.deb
which it failed about dependencies. Immediately, I typed in:
sudo apt-get -f install
which then installed all the dependencies for k9copy. Then I reran the dpkg install for k9copy:
sudo dpkg -i k9copy_3.0.3-1_vivid_amd64.deb
Hope this helps!
NOTE: k9copy was written for the K Desktop Environment, that is why it pulls so many packages.
