I use ImTOO DVD Ripper ver2.0.7
I struggled with that problem for a while until I figured out how to access the correct audio track.
I don't have the program in front of me so this is guessing at what I found but I think the audio channels were labelled something like ACX80 which had vocals on both channels, ACX81 was the MPX setting. I think if it was a multilanguage movie these channels would be the different languages.
The program assumes the user has some ripping expertise (not good for me) but the default settings seem to work well - except for that one audio setting.
The demo will run forever but only 5 minutes at a time
.
If you think I can provide any useful info just holler
