... Are you sure that roku sends NOTIFY messages continuously every minute?
Yes, for the 2 units I own ( pre Roku 2, running firmware version 2.8 ), I see NOTIFY messages from both boxes every minute or so.
And... According to the External Control Guide doc in the SDK (up to and including the 3.0 version of the doc), that's expected:
"... we multicast NOTIFY messages periodically (currently once per minute, but this may change)."
So, you've most likely got something in/on your network that prevents you from seeing the multicast broadcast NOTIFY messages.
Could be your router (not forwarding multicast traffic) or something filtering in-bound multicast traffic on your computer's network adapter.
FWIW, I've personally experienced one specific VPN configuration that un-intentionally filtered/blocked *all* multicast traffic (and therefore the Roku boxen's SSDP NOTIFY messages). The VPN sysadmin's intention was to prevent multicast traffic from traversing in and out of his network, but the VPN software (or possibly just a misconfiguration) was filtering out multicast traffic even from local subnet to local subnet. The moment I disconnected from that particular VPN, I started seeing the Roku SSDP NOTIFY messages again.
