I have converted ac3 & DTS tracks to WAV, Flac, Ogg Vorbis, & even MP3 & It strips it of all the Dialnorm & DRC & brings it back to its master settings.

I have used Handbrake & DVD audio extractor/ripper & it does the job well.

Hold on to your older DVD's many of them include the original mixes of the films.

here is an example of one i did for the Movie Poltergeist 2: The Other Side. here is the link: http://www.packupload.com/QLQVATPMD50

Here is another one, Titan A.E. in Flac from the DVD 2.0 Pro Logic file:

it is 499mb, so its pretty large

I converted the Poltergeist II AC3 2.0 Pro logic track to Flac & it sounds phenomenal! If any of you have the LD version compare my rip to the LD & I guarantee that it will sound nearly Identical.

I have done this with about 10 movies & they sound amazing.

Find the 1993 unaltered Star Wars Trilogy DVD's released in 2006 & convert The Pro Logic AC3 files to Flac using DVD Audio Extractor. You will be blown away by the dynamics, trust me!

remember to set the appropriate channels such as 6 channels for 5.1 content, & 2 channels for Mono & Stereo soundtracks when you rip.

you wont be disappointed once you try it
