Opposite to Clarkson's fast forward, you can also use May's Rewind button.
The shortest clip that I exploited was a McLaren lining up at the start and Clarkson boasting he'll win.
Press the L1 button when James May's Face pops up and it'll rewind to the very point the McLaren lines up.
As soon as May's face appears, rinse and repeat 10 more times until the trophy pops up.
