BRRip = An XviD encode from a Blu-Ray release (i.e. a 1080p *.mkv file).
BDRip = An XviD encode directly from a source Blu-Ray disk.
NOTE: While both BRRips and BDRips are superior to DVDRips, they are normally released in 720p resolution, since standalone DivX (*.avi) players do not support anything higher than this anyways. They should not be confused with genuine Blu-Ray rips in 1080p, which are usually done in native Blu-Ray files, or as H.264 *.mkv files.
BRRip vs. BDRip: Which is Best?
Technically there shouldn’t be much of a difference between the two - with one exception: Since BRRips are taken directly from a release that has already been ripped from a Blu-Ray disk (so it’s not a direct source), if there was a problem with the original .mkv, such as bad AR (aspect ratio) then it’ll be transferred to the BRRip, as well. True BDRips come straight from a Blu-Ray disk, which eliminates any problem with a middleman. However, this is somewhat of a moot point - the person/group responsible for the rip is seemingly more important to the end-product quality.
