Christoph, Well, Firstly thanks alot for those massive informations , really appreciate your help.
For now , I'm using two computers their specifications as following : The first One : Sun ultra-20 m2 CPU : amd 1.86 GHZ dual core Ram : 1 GB EThernet Connection : 1 Gbps Video card : nvidia 8400 GT 512 MB The second one with the following specifications : CPU: Intel core 2 duo 2 GHZ RAM : 2 GB Video Card : nvidia 8400 GT 512 MB Ethernet Connection: 1 Gbps The two computers are running ubuntu hardy with aghdvic and accessgrid3.1 . The first computer is prepared to produce DV using the DVideoService (using SimpleHDVideoService, I was not able to get the video from camera) , and everything is working seamlessly without troubles . I prepared the second one to participate in my node but the problem as mentioned before is that I'm not able to see any video from the first computer , the question now : you mentioned in your previous mail that DV uses different addresses for transmitting DV and HDV : The DV/HDV services provided by the aghdvic package use a different multicast address to the standard H261 video which is why the other participants could not see your stream How could i configure these addresses , in which config file i must edit these addresses ? P.s : I was trying to use DVideoConsumerService with the second computer but usually i got a pop-up message contains the following : "Add Service failed : DVideoConsumerService " Regards Muhammad
