I have problem with connection by JMStudio. Always when I try to transmit audio by this program I can't open session from second machine, I try connect between windows 7 - ubuntu and ubuntu - ubuntu but all the time there's "waiting for data" and nothing happened. I set as session adress ip of receiver. Also vlc can't open this sessions. Second problem is that when I try to transmit video file and I open it in JMStudio program crashed. Please help.
