On YouTube, "Tangled the full movie" is a quite poor quality, but it's English. And another video is HD, but it's Arabic. I've been looking this afternoon, and found (on a video site) the full movie of Tangled in HD in English.

If you want it, I'll paste it down. I know nothing about the site, I'm only for the movie. It does have bits of mistakes but are not even for a second. But you do notice them.
