Dvd Fab how to



I have been triyng to do the blu ray thing with little success, I’ve been doing Dvd 5’s 7 9s for a couple of yrs with few or no problems. Blu ray is a different game. I wish there was a Blu Ray tutorial. Anyway all my rips have been too large for the D9’s always over 9G, I know there is a way to get rid of a lot of of unneeded audio, etal, just don’t know how, any help?
If so please assume I know absolutely nothing as how to do this. T.I.A.
