Some that I know of based on codes from missav.
Rie is one of my faves too, and I managed to track down a slightly shortened, but 1080p, version of 071614-644. It's from a bluray rip of MCB3DBD-05, which is a compilation of 071614-644 and 073014-655. The rip split the scenes into separate video files, so I uploaded the 071614-644 portion to pixeldrain.
