hi..
I found this..is it old news..
About a week ago, Ryan wrote about a way that you could watch high-resolution YouTube videos by adding something on to the end of the YouTube URL. That is no longer needed because YouTube videos that are higher quality (not all are) have a link below the video that says “Watch this video in higher quality.” Some of you doubted whether or not you were actually seeing a higher quality video with the “trick” we first mentioned, so now this should put your doubts to rest.
well not so many high-resolution videos to see but somebody maybe have some use adding these settings..
