Brilliant! Works like a charm. Never actually worked with xml syntax myself, but I feel I should have figured this was the path anyway. The ampersand was shining bright red in the editor (who seems to know more about xml than I do)

Thanks for the superfast reply, now my real selection string also works and by putting these selection strings in profiles I can switch between different selection schemes on the fly, depending on e.g. the original language of the file (always want audio in that).
"-sel:all,+sel:((favlang|nolang|single)&(subtitle&!forced)),+sel:(subtitle&eng),+sel:(audio),-sel:(havemulti|havelossless),+sel:(special),-sel:((!eng)&(!swe)),=100:all,-10:favlang"
The above selects the best audio track in either english or swedish and all subtitles in either english and swedish but no forced track for swedish (don't know why I put that in but well..). It works most of the time movies in English or my own language (swe).
