About a week ago, YouTube started supporting a new High Definition format. First there was the ‘&fmt=18’ extension, then came ‘&fmt=22’. Full 1080P streaming. ‘YouTube’ and ‘HD’ previously were frowned at when both used in the same sentence, but to top it off, youtube now has a widescreen video player for their HD videos. Just look at these two stunning images from Gran Turismo 5, taken from fullscreen mode in YouTube. Video artifacting and noticable compression is very light compared to previous YouTube playback, and it is now actually watchable! Well done YouTube!

The fullscreen button finally has a purpose!
