I have worked out what was wrong. I have removed type=xml param and formated properly xml so it's recognised by sc_serv 2.2.1
But I found something different:
When I'm broadcasting from DSP (2.3.3 [build 201]) through djport2 I have set 'Name' field in 'Directory' tab so station name is changing on this one. After disconnecting station name remains the same instead of displaying streamtitle set in sc_trans
