So we all know that Let It Be is floating around. Personally, I didn't find the lack of quality too terribly distracting. There are two versions of deleted scenes reels around: one runs about an hour, the other runs about two. And then there's a Beatleg DVD set that was recently released called "Get Back: Stereo Video Album / The Winter of Discontent", which is pretty amazing. You can check out more information on that here and here.
