Hi Everyone,

I was digging the reason for the problem and came to know that Youtube has recently changed their URL structure. It doesn't disable youtube caching 100% but will give error for few youtube videos in transition. I am studying it and will make required changes in videocache to make it compatible with new urls.

Please check official youtube blog for more details. http://apiblog.youtube.com/2010/03/upcoming-change-to-youtube-video-page.html .

Thank You!
