Why is that?
simply their method of encoding.

Plus7 uses a more basic form of H264 encoding, that requires a higher bitrate to deliver the quality you see (though no where near as high as VP6 would have to go), while abc uses a more complex method which allows them to pack as high a quality with a much lower bitrate which while resulting in a smaller file requires more processing power to both encode on their end and a bit more vs Plus 7 to decode on our end, at least this is how I understand it. (look up CABAC, this is the main difference).
