So instead of editing my last post as planned, since you had already responded before I got back to it with my tested results, I will just reply here. I verified that the Override is working correctly for DRC. I tested DRC 0.0 and DRC 4.0 (the max value) both via --xtra --drc <value> and there is a noticeable difference in the video during scenes where the audio is quieter on 0.0 (on 4.0 it is louder / normalized).
A good example if anyone wants to do this test as well and has the movie I was using (500 Days of Summer) is around 30-33 minutes in, when the guy is doing the dance montage down the street (which is very loud), and then enters his work building and co-workers are talking / almost whispering (the elevator shutting + him talking + the co-workers are all very quiet). So on DRC 0.0, you will notice the drastic difference in volume, but on DRC 4.0 you will see the volume levels normalized quite a bit.

You don't see gain in my arguments because I don't set a value.
As for GAIN, I tested this as well at the same time, and both my movies were boosted with GAIN 5.0, and I can verify that my audio stream was loud enough for my receiver to run at 26. When GAIN is set to 0.0 (default), I typically have to set my receiver to over 34+ for movies, especially during the quieter scenes.
Thanks for your help OP! Again, this script is a HUGE help, and I appreciate all the great work here!
For anyone looking for helpful final scripts, here are the two I am going to be using now for DVDs based on this research.
NON-DISNEY ANIMATION MOVIES + ALL OTHER MOVIES:

Keep in mind that these are my final scripts for DVDs. I would definitely tweak them a bit for BluRays (quality for instance should probably be adjusted).
