I have an ipad 2 and a ip4s. I know there are plenty of apps that let ou set the playback to 1080p, but the native app doesn't let you choose the playback resolution. My problem is I go to a blog that posts videos from places like YouTube and Vimeo. The Vimeo player lets you choose hd if you want, but the YouTube app gives you no option, it just always plays the sd version. How can I watch the YouTube links in hd without going through th hassle of copying the URL and opening them in a non-official YouTube app?
