There is no place to store the info. Would you want LW to use Bitzi to check each file in your search results? Sure, it's possible, but I wouldn't want to have to wait for the process to complete.

Better to use the Bitzi link and a little common sense. After all, even Bitzi doesn't check each file, they simply list comments. Have you not seen where one person says the file won't play, and another says it's perfect? Would that be a tumbs up, or down? How about a great video that is mis-named? And many videos are what the name says, but are of lesser quality.
