I have an AC3 1.0 mono file.
When I convert it with besweet (into WAV for example), I get a Stereo file, with default settings.
So I decided to change the "stereo downmix" mode. And I choosed "mono" (azid(-s mono)).
But when I do this, besweet.log report a Dolby 2 downmix.
And the result is still a Stereo file.

And I don't know if it's normal, but when one use "--alt-preset" profile with BeSweet Gui (0.7b8, but previous version too), it's impossible to add options (you can check options, but they are not added to the command line).
For example "--alt-preset standard -m m" is impossible with BeSweet Gui.
Maybe it's not a "bug", but a feature (to avoid errors or something).
Btw, it's not really important.
