		Hi Simon,
		
		YCoCg is not lossless. You need an extra bit in order to
be lossless which is called YCoCg-R. 

	 
	Ahh, That's a trivial technicality :-) 
	 

 
Arghhh! Stupid Vaio laptops and their dodgy mousepad behaviour or
something...
 
I was planning to add that you don't need even need an extra bit to make
YCoCg lossless. ;-)
