Download Youtube Video

[jgp123]

Hi friends,

So far I had been downloading YT videos through a software(free) named YoutubeDownloaderHD which is giving excellent results. Very recently I have found a YT video(B&W) -480p(maxim. available resolution) which the above software failed to download. Most surprising is the YT video(Bengali movie) is not a paid one, nor encrypted & I could view entire movie(about 2 hrs.) in my Win-XP-sp3-IE8 browser. I failed to understand when I am able to see the movie, why the software could not download the video, though for other similar videos, it is still able to download. I am giving the URL of the video ---
"http://www.youtube.com/watch?v=5vbv85rTMVw"

I shall be grateful if any of my forum friends inform the name the youtube downloader software which can download this video.

Thanks & regards,
