How to reduce the size - ripping BR

I rip the National Treasure 2 and find the size is over 42GB. I wonder how can I remove those trailers, advertising, special features, credit (at the end), unwanted sound track and subtitle, and reduce the file size, but without changing the picture quality.

Can anyone show me the step-by-step from the begining (ripping) to the end (create a iso file)? Thanks a lot.

 

First this is to back up BR that you own.Second here is the guide that you are looking for please use the search function next time.

I did check this link, looks very diffical to do. Is there any simple way?

 

No there isn't any one click program yet & mite be a while before we see one.That way isn't hard more time consuming than anything.
