Actually you dont  You lift the center up slightly and the lower part will pull out easily, just dont pull the center part  all the way up that makes it harder  
   There was no way I could lift it out without taking the inner bit thingy off first...   
  
  
You were not trying hard enough then  Now where is the camcorder?  
  
The mistake people make is that they lift the center section then try to pull it out by tugging at the center piece then breaking the odd clip in the process. This makes it harder, once you pop the center lower it slightly and then lift the lower section up. Piece of ****.  
broke one doing it that way    couldn't for the life of me get it out, worked fine when I took centre piece out and then lifted out the lower piece... can film it tomorrow
