Protocol for the Tronsmart EZCast?

[Luke Bryan <luke32j msn com>]

Greetings,

I was wondering if anyone has had experience with a Tronsmart or similar device, through uPnP? Oddly enough, wireshark capture shows that when streaming a video file, it doesn't send XML over HTTP uPnP.
However, I got some interesting info over network from going to configure the device:

<?xml version="1.0" encoding="utf-8"?>

The script below almost works at the first time, but doesn't seem to send the packets separate, as EZCast does.
Is this a standard uPnP streaming protocol that GUPNP could help with, or is this some proprietary EZCast handshake GUPNP won't help with?
It looks like it sends packets ending with 0:0, 0:101, or 0:102 at times, I don't know if this is part of dlna/uPnP specification, or some proprietary protocol?
