@ duvinh
the stream is not hidden...
Streams on the homepage, is sent in many http-sequences that are stored on your PC (same as german JoinTV)
at the IP box of Vietface but it's different - there are (changed) streams as before,
but the address is not read, we dont have the box unfortunately
edit:
http://vf10.aditmedia.net/iv/channel/1005/connection?x-token=premium&client_type=rtmp
the Link from Streamadress, open in your Browser and click update... and kick again
you see in the xml - the token and sid change everytime - but i found only one channeladress
I think you have to look for an alternative
