just to let anybody interested know - I am currently wrapping up with deliveries for the German kids' TV series STURMFREI (second season, broadcast on KiKa Kinderkanal). Nuendo 5.5.3 handled the full in-the-box editing, design and mix and went pretty smooth, apart from a few automation bugs here and there.
Batch export was a major advantage on this one, hands down.
The series can currently be viewed on kikaplus online too. (Season 2 starts with episode "Beziehungsstatus single", episode 13 I think.)
