Problem in server/client , connected but no video

#1
I have wireless lan , the connection is good
I made a connection between server and client ,
the client is connected to the server and i can change the channel but the video doesn't appear , (tried all types of decoders)
now , i am totally desperate. three days of installing , uninstalling standard and pro version ( latest version ), and nothing but fail, fail and fail
:cry:
Is there any way to view the video on the client screen
