Broadcast TV OK with Eric Idle (4,4)
I believe the answer is:
tick over
'idle' is the definition.
(I know that idle can be written as tick over)
'broadcast tv ok with eric' is the wordplay.
'broadcast' indicates anagramming the letters (letters scattered or cast around).
'with' means one lot of letters go next to another.
'tv'+'ok'='tvok'
'tvok' after 'eric' is 'erictvok'.
'erictvok' is an anagram of 'TICK OVER'.
(Other definitions for tick over that I've seen before include "(Of engine) run slowly in neutral" , "Run smoothly (or very slowly?)" , "Just keep going like idling engine" , "(Of engine) idle" .)
