We'd like to strip audio-streams aswell, so we select the second option too.
I also already specified the destination directory, and the location of the *.m2v file we'd like to remux.

If you don't need the Menu, and want to have a Movie-Only DVD, then you might want to check the option 'Create new VIDEO_TS.IFO & VTS_01_0.IFO'.

Press 'OK':

We want to keep Audio stream 1 and 2, and subpicture stream 1 and 2, so select the second streams:

 As you can see, the Menu-VOB's are missing! So copy them manualy to your destination directory:

Now you have to check out, if you will need some of the other files, especially if you want to keep the original Menu.
