I've been working on a custom profile for a few days, but my target device does not support the "Dolby Prologic II" audio that DVDFab always chooses by default, so I want the profile to specify that A) Only stereo is supported and B) Stereo is selected by default.
The Readme that comes in the DVDFab install folder mentions device_channel_ability and channels flags, but these don't appear to have any effect. I've also seen some profiles that had a channel parameter in their audio tag, but I haven't seen this make any difference either.
Is there an undocumented parameter that can force DVDFab to choose Stereo under Audio Format by default?
