scan & Tiuone + local view

I us e sacn & Tioune V0.1p and havee no problems in receiving the udp stream on other computers. ( I chose adress 230.0.0.10:1234 and changed the ini-file)
But if i recall the udp-Stream on the computer where scan & Tioune is running, I have no decoded picture and also no picture in the program itself.
What have iI to change for proper function??
