I am pretty sure that the payout per video is 40 micro bitcoin (it was recently dropped from 50 micro bitcoin). Unfortunately to see this number, you need to register. It's a common amount for watching one Virool video (e.g. another site ABitBack pays only 30 micro Bitcoin per Virool video).

I am surprised too that the error hasn't been corrected yet. The difference is 10 times, which isn't insignificant.
