Basically within the law, if you approach a set of lights and every other car is stopped, you can legally split either side of the line (provided you don't break any other regulations)
If the right lane is moving, technically you must stay in the left lane (doesn't matter if the left lane is moving or not, as long as you are passing them on their right). Or, as you suggested you could pass on the right side of the right lane.... but that's risky in itself because there is more chance of them deciding at the last minute to turn right.
The only time you can overtake on the left side of a vehicle in the same lane is when it is turning right or stationary.
Having said all this, its all crap, and incredibly unlucky/stupid that you got pinged. Laws should be created and enforced based around common sense. The only thing wrong with splitting is cars get shitty because they cant do it. As for your infringement, if your video recording shows all the right lane cars you pass as stationary then I'd say you're lawfully in the clear.
