this is logical, paying players have the second video. e.g. when I watch the vids from my teammates 25*2=50 vids. A none paying player without + account when he/she watches from 25 players the vids it might be 30 in total because there is a chance of the second vid. That's already a difference of 20 vids.
There's very little incentive to watch the first video if you can't watch the 2nd...so probably even lower than that.
