    this special case only working for test-r
    It's just an example. The same process can work for any channel.

    but not if one/two service had similar and no one knowing the pids for video audio
    The PIDs can always be found in the log file, or on KingOfSat, or with various other tools. If I recall correctly, DD may even have a special tool that produces m3u playlists for TV Server.

    Thanks for the solution: It works flawlessly. Test R now switches without any problems. I'm excited

    Specifically, I need the dynamic PMT for the channel
    HD WDR food on Astra 19.2 1H / 1K, RE / 1L / 1M / 2C. At 19:30 will be switched to the regional program.
    The URL:
    rtsp://@192.168.100.80/?src=1&freq=12421&pol=h&msys=dvbs&sr=27500&pids=0,5540,5501,5504,5502,5503,5506,5501,18,17,16

    How is the URL then?
    Just insert the 401 and 402?
    Or first create log file and check?

    I'm asking because I'm a layman. I use Google Translate for a better English.

    DD has a tool: Digital Devices Store
    Konfigurations und Service Tool für Octopus NET / Rack. Erstellung von M3U Listen für MediaPortal und VLC Player. Erstellung von MultiCast Listen für Octopus NET

    Best regards

    @KaiDiefenthal: How do I get the information so I know what I need for pids?
    The link to the frequencies does not indicate any pids.

    This is the easiest option for me to give you an answer that will definitely work.

    The log file needs to include the PMT change so that I can see all the PIDs.

    Thank you! :)

    So, we have the channel URL at the start:

    From these we can find the required URL. :)

    Base for all channels:
    • 0 = PAT (always needed)
    • 16 = NIT (needed for scanning)
    • 17 = SDT (needed for scanning)
    • 18 = EIT (needed for EPG data)
    Initial PMT:
    • 0x87b -> 2171 = unknown, probably not needed
    • 0x942 -> 2370 = unknown, probably not needed
    • 0x948 -> 2376 = unknown, probably not needed
    • 0x157d -> 5501 = h.264 video/PCR PID
    • 0x157e -> 5502 = German MPEG 1 audio PID
    • 0x157f -> 5503 = "MIS" MPEG 1 audio PID
    • 0x1580 -> 5504 = Teletext PID
    • 0x1581 -> 5505 = DVB subtitles
    • 0x1582 -> 5506 = German AC-3/DD audio PID
    • 0x15a4 -> 5540 = PMT (needed for tuning)
    Updated PMT:
    • 0x1f8 -> 504 = Teletext PID
    • 0x259 -> 601 = MPEG 2 video/PCR PID
    • 0x25a -> 602 = German MPEG 1 audio PID
    • 0x87b -> 2171 = unknown, probably not needed
    • 0x942 -> 2370 = unknown, probably not needed
    • 0x948 -> 2376 = unknown, probably not needed
    • 0x15a4 -> 5540 = PMT (needed for tuning)
    Removing the duplicate and "unknown, probably not needed" PIDs gives the following URL which should work all the time:
    rtsp://@192.168.100.80/?src=1&freq=12421&pol=h&msys=dvbs&sr=27500&pids=0,16,17,18,504,601,602,5501,5502,5503,5504,5505,5506,5540
