Your chart doesnt really tell anything about BD movies ripped into MKV's.
A 90-120 minute movie compressed into 4-8Gb is going to have a bitrate of aprox 5-12mbps, that is just plain math.Example:
4.7GB equals 38Gb (Giga BIT) equals 38000 Mb
100 minutes of movie equals 6000 seconds of movie.
38000 Mb / 6000 s = 6,33 Mb/s (this is of course combined bitrate of audio and video stream, but I ignore audio in this discussion)
It doesnt matter if the file is mpeg2 og mpeg4 (x264) the bitrate
of the file is the same. The difference is in quality of compression, mpeg2 at that bitrate gives a crap HD-picture, that is why PMS uses a much higher bitrate when it transcodes to mpeg2 for streaming.
The math works both ways, so if you want to save a transcoded file at 25 Mb/s the resulting file will be 4 times bigger than the original file, around 20GB.
