Use ONE of the following DIRECTLY AFTER the YouTube URL and you will see a hi res version of any video that is available with that option (not all are) Here are two examples of the quality WITH the f&mt=6 at the end - to see it in default mode, take the &fmt=6 OUT of the URL http://youtube.com/watch?v=0Jj5sgJbux0&fmt=6 http://youtube.com/watch?v=TrceNI6UUmc&fmt=6
Not really but it should help youtube bring more traffic in, one of the reason I never really cared for youtube was the quality of the videos.
