Tvheadend

Hi there, i just checked the board but didn't find what I've been looking for.

I'm using a FritzBox6490 Cable and I've exported an m3u playlist. I created a IPTV Network in TVH and one Mux per Channel from the m3u (see images attached). Watching telly is working fine as long I'm not recording at the same time.

Previously I've been using the SATIP setup with 4 Adapters. Each Adapter had a unique IP Adress attached, which is necessary for the fritz box. I reckon that's the reason for my problem. Is it possible to configure individual IP addresses per IPTV Stream?

Kind regards,
Kai
