Some iptv channels get reported as Mpeg1 when using serviceapp with exteplayer3, when they are really Mpeg2.
For most boxes this isn't a problem, however Vu+ Zero4K does not support Mpeg1, so even though the video is Mpeg2 (verified using Gstreamer instead), you don't receive the video, only audio when using serviceapp.
