Unfortunately, as our platform does not support Windows media, your only option would be to output directly to another machine running Procaster or a similar encoding software.
However, Tricaster Pro machines should support Flash. Please be sure you are using the Adobe Flash setting as opposed to Windows Media Push or Windows Media Pull. Also, you may want to check that you are using the latest Tricaster software from NewTek.
Please see more about broadcasting with a Tricaster in our user guide: http://www.livestream.com/userguide/...wTek_TriCaster
