Tvheadend

Check firewall. It seems that it does not forward UDP packets.

It works, I have a working setup here. Wrong parameters cause it to not work though.

Well, double fail on my side:

tvheadend needs UDP packets being send from the SAT>IP to tvheadend
I had to allow UDP connections from the AVM DVB-C UDP ports 5000/5001 to the tvheadend server IP to make it work again.¶

Why streaming with the same rtsp links would work when entered in VLC directly (tvheadend server machine)? Beats me
However, Kodi as client works just fine!

Using the M3U files from the "play" link doesn't work at all
For debugging I used the "play" links from Configuration > DVB Inputs > Services which unfortunately don't work at all (even after I got my overall setup to work again). Therefore it didn't even work (from my debugging perspective) when both tvheadend server and DVB-C input would be in the same /24 network.¶

So, lesson learned: use Kodi for debugging the individual TV streams, not VLC and the M3Us provided by tvheadend.

I hope this will help someone stumbling over the same problems as me some day...

playlist for client can be found on

It should work. But the lifetime of the authentication ticket is limited to 5 minutes, so you cannot use those files after this.

Use user:passwd authentication or the persistent authentication code.
