Never tried this with a QT movie, but it has worked fine for me otherwise:

FN VC
  SOUND END
  DIM pBlock.100
  Pblock.ioCompletion& =  0                       'completion rtn
  Pblock.dCtlRefNum%   = -4                       'drvr ref num
  Pblock.CsCode%       =  2                       'control code
  Pblock.CSParam%      =  sndLevel                'sndLevel 0-7
  OSErr = FN CONTROL(@Pblock)
END FN
