BeSweet is a CLI (Command Line Interface) program.
You have to run it from a console window (aka "CMD").
There is a GUI for it, but you also need to install other filters/plugins/libraries as well.
DVDFab, free is a good option.
Another thing you can do is use AnyDVD (trial/payware) or DVDFab (free version) to decrypt the disc and then use eac3to to extract the AC3 track (track normalization will be removed to match audio levels for all other formats for encoding). Or simply use -demux (but this will extract the video as well).
eac3to is also a CLI but there are several GUI's available and only 2 that are updated.
Another option with AnyDVD (or the Free version of DVDFab HD Decrypter) is to use PGCdemux to extract the AC3.
DVDFab HD Decrypter 9.0.6.0 (free version)

NOTE! The decryption, DVD to HDD and Blu-ray to HDD, is FREE, if you want more features then it's a trialware. And it may take 1-6 months until it supports NEW DVD/Blu-ray releases.
PgcDemux 1.2.0.5 (NO LONGER DEVELOPED)
http://www.videohelp.com/tools/PgcDemux
PgcDemux is no longer in development but it doesn't need updates.
The DVD structure/format hasn't changed; just the copy protection has changed.
PgcDemux requires the DVD to be already decrypted. :smrt:
