I paid once for fraps and get regular updates. Dont know how much it costs nowadays though.
An alternative is to set up a webcam that will cover the whole screen. R1pper did that and his monitor is a monster, so it is possible to get a good enough result that way.
See how you go, and let us know when you have posted a vid so it can be checked out. I hope you understand that due to limited tools available, we admins have to use our judgement in some cases where things are not clear. This does mean inconvenience to some players such as yourself, but that said, we have also found that most honest good players want the opportunity to prove that they can play and get the scores that bought their gameplay to our attention in the first place.
Good luck and I am sure we will see something soon.
Cheers
