UDP / Multicast streaming in Monterey

[aliquot]

Hello all -

My workplace has a number of multicast streaming device which we use to play video in common areas. I'm finding that none of these will open on any machine post MacOS 12.2 or so. I have tested on a number of machines, both Intel and Silicon, and all seem to stop playing the UDP stream once they are upgraded to 12.3 or later. I'm curious if anyone else is experiencing anything similar or can test?

Thanks
