I want to watch an entire YouTube playlist at fullscreen. The playlist consists of 9 videos and every video's quality can be chosen from 240p all the way to 1080p. I want to view the playlist at 720p, but every time I choose it while watching one video and it reverts back to 1080p when it switches to the next video, though in my "Settings" I have "always play at HD" unchecked. I want to play it at 720p because my internet connection can never play 1080p properly. Is there a way to watch the playlist at a constant quality throughout?
Environment: Windows 7 and Internet Explorer 8.
