Drama and a technical issue in the Ashes yesterday, with Alex Carey scoring a welcomed century as Australia ended the day at 326-8, but he should've been out when he was on 72.

England used a review on a caught behind as they thought they heard a sound - the microphones on the stumps showed a clear noise but was shown on the replay as happening before the ball passed the bat resulting in a not out call.

Afterwards, Carey admitted that he had hit the ball and the company that owns Snicko concluded that the operator at the time must have chosen the incorrect stump mic for audio processing. 

Sir Ian Taylor is known for his work with televised sport - and he joined D'Arcy to discuss.
