No but i used vmix livelan option to do this on Monday as for some reason multicast is not working across our vlans
It has a 60 day trial as well.
Be aware it will introduce a delay of at least 10 seconds due to how it streams.
Another option is to use vlc but use the http option as the destination when creating the stream, then on the other pc you just use vlc with media->open stream enter http://servername:port
Again this will introduce a delay but it is better then iplayer!
