DVD with multi films how to copy

HI. I’m new here. From your forum I have learnt to back up my DVD9 to dual layer disks using DVDdecyripter and all works great, thanks. I need to know how to back up a dvd9 which has several short films on, but only back up say 2 from one disk and one from a second disk. Back up needs to be on a dvd5 but with no compression. DVD shrink is good but compression at times is too much. Can anyone help? pref free software.
