I know bitrates can be overrated but the truth is when a bitrate is very low, like single digits, it can have an effect on PQ. I've seen discs where the bitrates are very high but the PQ is still average. I actually put on sony's underworld last night after watching the matrix movies. for comparison since both were shot visually the same. the transfer for underworld, which is excellent, suprassed the matrix movies in blacks, fine detail, and 3D pop. I saw compression issues. SQ was almost a wash, I had to volume match since truedhd tracks are softer than dts ma and pcm tracks. I hate volume matching, I like the volume in a general area. hence, I gave that advantage to underworld. matrix trilogy was good but I place it along the same tier as batman begins, too soft.
