Hi

I have a Problem with a Server/Client constelation.
On the Server TV works without a problem.
on every Client on the Network (Gigabit wired) i got a black screen with no sound.
Over the Info-Panel i see the rtsp://192.168.1.253:6666/stream4.0 link. (JPG attachment)
i changed the port to 6666 as i read on the forum the standardport makes trouble.

when i open this link in VLC after about 3 Seconds the Picture and Sound shows up
so i think its a codec issue? i tried without any codecpack first. then i installes SAF 6.0 on the client and the server and tried almost every codec constelation.

any ideas?

Same Problem, it stopped working somewhere in 1.2.1 or 1.2.0. Since then I get the same Problem. MediaPortal Clients are Black/no sound but stream seems to be received if i see the network stats. VLC Player (MPTvClient) works fine.

Help anybody?
