No, I don't have OP's problem. Just that Visual TraceRoute is not pinging from my machine too, it's pinging from about a hundred machines elsewhere in network of different ISPs. It's pretty useful tool to identify the problem from the target webserver to major backbones.
Whenever I heard there is network issue from oversea customers when visiting our company's website, this is the item to check after verified the problem is not on our webserver (memory stress etc.)
From the statistic, we can rule out the possibility of networking problem from Channel9 host to backbone. Now unless there is a problem on the webserver, it's likely to be a problem from the OP's ISP, or his own machine.
Btw, since I can watch the videos instantly without buffering (for those who don't know, I live in Hong Kong), I doubt it's problem on the webserver. So....
EDIT: Btw, I found it's hard to believe there could be a problem when watching video in Hong Kong. Even if you neglect the fact that out of the 7 undersea fibers connecting Asia and America, 4 of them connects through HKIX in Hong Kong, most ISPs in Hong Kong uses transparent proxy. So unless you're the first one watching the video from your ISP, instead of streaming from the C9 server, you should be watch the streaming from the proxy server.
