I think I may have mentioned this before but my idea is that the video referees should be isolated in a booth with no exposure to the game until they are required. Then, when a decision needs to be made, they get a call, the monitors turn on and replay the footage of the incident to be adjudicated on.
My reasoning for this system is that too often, the video referee's decision is influenced by the scoreline or the momentum of the game. How often have you seen a blatant "no try" be given as a try when the scoring team is well behind? On the other hand, when the game is close, the video ref is much less likely to award a contentious try.
I also feel that the video referee will often make a ruling to "even out" or "square up" a lopsided penalty count or bad decision. Look at the Cowboys V Manly game that everyone is up in arms about; the try the Cowboys scored to even up the score came after a blatant Cowboys strip, which was shown to the whole crowd and TV audience in close-up and slow-mo. Also, the last pass thrown by Thurston was clearly forward. I have no doubt that the video referee, having seen these mistakes by the on-field officials, were always going to be more inclined to rule in Manly's favour in order to "right the wrong".
There would have been concerns that those bad decisions let the Cowboys back in the game and would cause controversy if they cost Manly the game (which it would).
If the video ref's were not aware of those previous bad decisions and the scoreline at the time, I doubt they would have awarded the Foran try.
