Hi, Ive got specifical problem with mencoder under windows xp sp2. When i use mencoder or mplayer to record or play streamed video from udp address, then i cannot at the same time record or watch other streamed videos from udp. This error will always shown: Failed to connect to server udp_streaming_server failed File not found: '239.194.10.11:1234' <%27 at 239.194.10.11 <http://lists.mplayerhq.hu/mailman/listinfo/mplayer-dev-eng>:1234%27> Failed to open udp://'239.194.10.11:1234. <udp://%27@239.194.10.11:1234.> Interesting thing is, that during using mencoder or mplayer,VLC does play or record from this udp source! I think there may be some windows mini port problem with deallocation of UDP address. I hope you will help me, Thx Pavel
