In both DVB Viewer and Tvheadend, I only see
one DBV-C tuner - but I think that this is ok since I enable only the DBV-C section of my TV to be used with the TV>IP server.

What I now did (to the best of my knowledge):
*
Step 1: I did a fresh re-install of Tvheadend.
*
Step 2: Tvheadend found the Panasonic TV>IP server at its IP and displayed it as a folder under "TV adapters". However, it did not display a concrete tuner under this folder when "Tuner configuration" was set to "auto". I manually changed this option as to "DVBC-1", and my DVC-C tuner popped up. Additionally, I actived "RTP/AVP/TCP (embedded data)". The other options in this sections were left untouched.

Step 3: In the tuner parameters, I enabled the tuner and connected the network (I did that in the next step and came back to connect the network...). I set "network type" to "DVB-C" but Tvheadend seems to frequently forget this setting or does not correctly display. I left the "UDP RTP port number" to zero while I assume that Tvheadend will use default values then. (If I would need to set this, I could set this to 554 since I now that my TV is listening on this port.)

Step 4: I created a network named "Kabel Baumann" and attached it to the tuner (see step #3). I left "SAT>IP source number" to be zero. I guess that this is ok.

Step 4: I manually created a mux at frequency 122 MHz, symbol rate 6900 kSym/s, QAM256. This should be a valid mux confirmed by both the channel list of my tv cable provider and by the channels found by DVB Viewer Pro.

Step 5: I then enforced a scan in the "networks" section of Tvheadend.
*
The result is that Tvheadend keeps stumbling over this "RTSP error -5 (input/output error)".

I read in another forum that it might have to do with the port 554 used by my TV>IP server. Since Tvheadend is running as a normal user on my Pi, ports below 1000 cannot be accessed by Tvheadend. Maybe running Tvheadend as root could be a solution?
