The router has absolutely no effect inside your LAN. There it is just a switch.to test your router , I would seggest start watching a recording on the server and connect to that stream via vlc from the client (stop mediaportal all together). The network connection string to use will be in the MEdiaPortal log in the way of rtsp://serverip/xyzabc. VLC uses no codecs to display video so it will assist in proving the router.
Wow Charli, you are going a bit too fast for me. I don't have enough knowledge of logs to know what to use
So I install VLC on the client, but where do I start this stream then? How can I instruct VLC to open the stream?
The VLC suggestion is still a good one to test the LiveTV (RTSP) Streams created by the TV-Server, on your local client PC.
And i recommend that you upgrade to RC4 as soon as possible.
