Reproduction requires freedom of movement and finance (8)
I believe the answer is:
playback
'reproduction' is the definition.
'freedom of movement and finance' is the wordplay.
'freedom of movement' becomes 'play' (as opposed to time spent in a classroom, say).
'and' means one lot of letters go next to another.
'finance' becomes 'back' (backing is a kind of financing).
'play'+'back'='PLAYBACK'
'requires' acts as a link.
(Other definitions for playback that I've seen before include "Reproduction (of a recording made earlier)" , "What records are for" , "Reproduction of recorded sound" , "rerun" , "VTR feature" .)
