Files like this are commonly found on torrent trackers or file-hosting sites. If you are looking at this file, keep the following in mind:

: This is a high-quality format. A "remux" takes the raw video and audio streams directly from a Blu-ray disc and puts them into a new container (like .MKV) without re-compressing them. This results in the best possible picture and sound quality, identical to the physical disc.
