Does anyone know if the Unicron Wars DVD's which are split into collections such as 'Aramada - Collection 1', 'Cybertron - Collection 2' etc between them contain all the episodes from those seasons?

Too expensive for me to buy at the moment anyway (to get all 6 collections it would come to around $300) but would be good to know for future reference.

Also, does anyone know if this Rescue Bots 4 DVD pack contains all of season 1 on it? Many thanks.
