Starting LibreOffice Impress or Draw initiates constant IPTV incoming traffic
Source: 10.102.19.18 Destination: 239.0.0.1 UDP UDP:SrcPort = 49152, DstPort
= 1234, Length = 1324 {UDP:10, IPv4:9}. Its one of IPTV channel.
This makes Office lagging. Seems it concerns Remote Control feature because
it also works with 239.0.0.1 server. Is it a bug? How can I turn Remote
Control feature off?
