Programme shown again about organic fuel (6)

I believe the answer is:

repeat

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

'programme shown again' is the definition.
I can't tell whether this definition defines the answer.

'about organic fuel' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'organic fuel' becomes 'peat' (I've seen this in another clue).
're'+'peat'='REPEAT'

Can you help me to learn more?

(Other definitions for repeat that I've seen before include "Say or perform again" , "Duplicate" , "Iterate" , "Reiterate" , "Say, do or occur again" .)

I've seen this clue in The Sun.
