After having the Wetek play 2 for 2 days I managed with the help of OSTool 2.11213 by Guru to get things going. The Wetek Play 2 finds the smartcard in my dreambox and alll is working like a charm. For anybody who just bought the Play 2 and is looking for the right Oscam, this works nicely. Just wanted to share this because it might save you a lot of searching on the net :-) If you want this oscam only for sharing your own card from a dreambox to the Play 2, just create a new reader (as shown below) in the oscam.server file and delete all other entries in the oscam.server file.
