Tvheadend

Hi, I searched the forums but can't find how to hookup 2 tvheadend servers through IPTV, I went to DVB Inputs > IPTV and added a IPTV source like this:

Channel name: "Some Channel" / Interface: "eth0" / Group: http://user:[email protected]:9981/stream/channelid/12 / UDP Port: 1234

But this doesn't seem to work, is that the correct syntax?

Thanks
