Advanced streaming software?

Hi.

Wanted a streaming software witch could send few streams to different servers in different resolution, have more options in video settings, formats etc. etc. Now we have PC with two SDI inputs (BalckMagic dual SDI).

Now we use FMLE, we used Wirecast (didin't liked). Hardware solutions are not in the list. What are opportunities? What does broadcaters use from software? Is it possible to use ViewCast software used in Osprey cards or Nigara or from analog DigitalRapids products?

Thanks.
