[QUOTE=surindersharma;1043736]I suggest you you tube is the best[/QUOTE]
As has been pointed out elsewhere in this thread, YouTube is NOT a search engine; it is a video hosting resource with an integrated search facility allowing users to search for videos ON YouTube.
On the other hand blinkx[I] is[/I] a specialised search engine; submit your search term there and it will return results from YouTube, GoogleVideo, MetaCafe, MSN Video, DailyMotion and dozens of other video hosting sites.
Blinkx presents an opportunity to view videos from [I]all [/I]of the major (and many of the smaller) video hosting sites in one window. Try it - you might be surprised at just how good it is.
