with A2DSource and DSS you get downmix because output audio channels configuration is driven by the direcshow filter mixer (i.e. ffdshow). FFMS instead needs a proper audio channels remixing using AviSynth. In the next release I will add this capability (thanks to Tebasuna downmix functions
).
PAL SpeedUp works only if input video is detected as 23.976 fps. In your project the input source is VFR (variable frame rate). But you can force AVStoDVD to believe that source title has 23.976 fps. Just use 'Title'/'Edit Source Title Info'/'Video FrameRate' option. Remember to toggle on 'PAL SpeedUp' from 'Preferences'/'AviSynth' before adding the source title.

if menu is Static, then audio will not loop. To have menu looping you have to make a Motion menu, with video and audio.
