Not all videos of a certain resolution and format are alike. There are 
other factors that influence how easy it is to decode a video. A few are:
- bitrate (at any given moment, depending on motion and such)
- codec features used (deblocking, B-frames, etc)
- framerate (probably not relevant here, but worth mentioning)

There are probably others, but that's what came to mind.

Arguably it shouldn't be, but it is, for now...

That's the way the world works. :)
