The second link has exactly one person clearly stating that they've received zero launches and zero video plays. There is a second person that states "Yeah, same here. We had a workflow setup to send us notifications if any new used the app and received none." Notice that he/she doesn't mention video plays.
So, in total, we have exactly one person that says that they've received zero launches and zero video plays. If I've unfairly characterized the data behind your links, please let me know. But that's all that I can find.
In trying to find out if they have a valid complaint, I've discovered that the person behind that complaint is responsible for a significant portion of all of the discussions and complaints at the challenge site.
One thing is clear: their submission is in the same area as the winning entry. In their shoes, I might be disappointed for that reason alone. But for the sake of transparency, here are the two entries:
The winning entry (which is admittedly being evaluated to see if they conformed to all rules):

The entry for the person or group that claimed that their video was never viewed: http://vimeo.com/79921465
In any case, I encourage you to look at the two videos and tell me if you think there was an injustice with the rank ordering.
