Repeat broadcast? (5)

Ross

I think it could be either:

resow

rerun

I'm a little stuck... Click here to teach me more about this clue!

But I've got no explanation for this one! Could you help me understand?

(Other definitions for rerun that I've seen before include "Show or perform again" , "Broadcast or print again" , "Second broadcast" , "Repeat performance" , "Put on again" .)

I've seen this clue in the Sydney Morning Herald and the Evening Standard.
