Simple: It was encoded with a lower average bitrate. A lot of people struggled to play 1.0 smoothly, so we encoded the later version at a lower bitrate and heard fewer complaints.
Yeah, I noticed that. You have implemented a more dynamic bitrate compared to V.1.0 which was more close to 80 Mbps regardless of content, whereas V.1.4 jumps all over the place and actually has a higher bitrate compared to V.1.0 where it is needed (i.e. bright scenes) and much lower when there is much darkness in the image.
Thanx for the response.

Yes 1.0 was constant bitrate, 1.4 is variable for greater efficiency.
