Ive been using MakeMKV, but I find the resulting files are between 4 and 5 GB.

Am I doing something wrong?

That's a single layer DVD.

A single layer DVD holds about 4.7GB.

Chapters, by convention, are a gigabyte a piece.

Two hour Hollywood content uses dual layer DVD
and holds 8.5GB or so. The disc has 9.4GB capacity,
but it need not be filled right out to the end.

On the dual layer DVD, the "layer split" has to be
placed so the two sides of the DVD are "relatively
close in size". If you see odd sizes for the
chapters, part of that is engineering the layer split.

When people rip Hollywood content (8.5GB), they re-code
and either change CODEC or change bitrate in the encoder
to further compress the movie. This then, allows a new
DVD to be prepared using 4.7GB single-sided media.

At a bare minimum, the ripper uses DeCSS to remove the Content
Scrambling System. Hollywood media has encryption, and DeCSS
can remove it. Medias are protected with all sorts of other
stuff. Maybe Casino Royale has a kind of Windows malware on it.

But for junk, like a DVD from the delete bin, just DeCSS is
sufficient for those. I'm not a movie collector, and my
"test disc" is Animal House, and that rips fine using
just DeCSS in the selected tool.

This will give some names and things to research. Makemkv
is mentioned in the first one. I may have tried that at
some point, and it ripped the two "features" on my disc OK.

My video card has a nice encoder... if you don't care about
quality, it goes quick as snot (11x real time). When someone
asked the other day, "how to compress 1TB of noisy non-descript
video", that's what I suggested. Video purists don't really
like hardware encoded content all that much. They like CPU
encoding (2-pass) better.
