multi-pid multicast stream problem with vlc 3

[vgrig]

We're retransmitting multicast streams on our network using vlc and vlm.conf
Streams contains mutiple programs, which we separate with vlc and retransmit one streams per multicast IP.
This used to work with v2, but doesn't any more with v3 - when i play out retransmitted multicast stream, vcl opens all programs in separate window. What changed? VLM wiki page is outdated.
Please help!
Below is vlm config (again - works perfectly with vlc v2. I also tried from command line with cvlc - no luck)
