The movie after remux often has H264 video codec.

The orginal movie has AVC, or VC-1 video codec. I don't intend to backup my Bluray disc in computer, just want to resolve my doubts. But i dont understand: the orginal movie has AVC, or VC-1 video codec. They said Remux will keep orginal quality. And the size of movie after remux isn't too small to orginal disc. With this method, they can choose to keep disc menu or not, and remove some unnecessary stuff like some audio streams. If the quality cant be keep, why don't call "Encode" or "Rip" ? So, will this backup method keep orginal quality of movie? I doubt that, because the size is too small (9GB) to orginal BD disc. They shrink one Bluray disc (about 40-50 GB) into 25GB, and enven 9GB (they call: BD 9).

I see somebody backup their Bluray movie in HDD computer, they call "BD Re-encode". I have some questions about bakup Bluray.
