Thank you for the URL!
I entered the stream URL https://rt-ger.gcdn.co/live/rtdeutsch/p ... 500Kb.m3u8 into the Internet TV search box of ProgDVB Professional 7.17.01. The result was: not supported format. Is there a solution within ProgDVB?
"RT News" (Russia Today) started a new stream in the German language, "RT DE". I don't find "RT DE" in the list of IPTV streams at this moment. Is it listed nevertheless? Or is it possible to add this stream to the IPTV list?
