looks to me like this is a bug in DVD-Slideshow.

at the line:
"ffmpeg -threads "$cores" -i "$tmpdir/audio1.wav" -y -vn -ab "$audio_bitrate"k
-acodec ac3 -vol "100" -ar $audio_sample_rate -ac 6 "$tmpdir/audio1.ac3" >>
"$ffmpeg_out" 2>&1"

By using -ac 6 it's trying to always upmix from whatever the source is to 6
channels, which is not supported for all channel layouts.

Filing a feature request to add more generic upmixing support would be fine,
but this does not appear to be a bug in Libav.
