Fail to download a video clip(jaksta, Tunebite 7, WM recoder)

[h6woo]

Hello everyone
I was struggling to download a video file from the web and it seems I have reached my limit.
I tried to get URL of the file using URL Snooper and Unsniff but I failed to do so.
I was googling and found this site. I downloaded programs such as Jaksta, WM Recorder, TuneBite 7 as many of you recommended.

Using Jaksta, I got the URL but the file cannot be downloaded somehow. It kept buffering.
So I ran Net Transport to download the file but it said I have no permission.

I can watch the video on the web without any problem(only IE works.)
When recording programs such as jaksta, Tunebite 7, WM recoder, and non-IE web browsers are on the process, the video will either not play or terminate the programs. Recording the screen would not work too. It would be terminated.
Here is what I have found

User-Agent: WMPlayer/11.0.5721.5251

I really appreciate your attention and help!
THanks
