I have not recorded or watched MotoGP so can not comment directly. However

In 2010 I complained to TVNZ via their website about the terrible comb 
artifacts on an episode of Corornation Street

Their reply in part:

We regret the poor quality of 'Coronation St.' on Tuesday night.

We have investigated the cause and are now confident it was an isolated
incident. (The file which had been created from the supplied tape had an
incorrect setting, resulting in 'field dominance' issues.)

So yes TVNZ can get it wrong!
