Well that was fun.
I set up wifi internet sharing on my mac and routed the LG through it and ran Wireshark against the interface.
First thing the LG does is send a dns query for startup.vvond.net. It gets back 208.79.221.221 which is an IP at peakwebhosting. Vvond is the original name of Vudu I read and peakwebhosting appears to be associated with Vudu as well.
From then on all traffic is https between the LG and 208.79.221.221.
The traceroute bewteen my home and that IP is
