This minor change suggested by Martin Wache sorts out my incorrect colour
issue when the GRAB command is used with softdevice when using Via CLE266
hardware decoding.
I've not looked into what pixel[1] and pixel[2] actaully do in the
PicBuffer structure but this small change fixes the GRAB command so that
I get correct colours. It seems to work for me with and without picture
mirroring or deinterlacing (i.e. using some form of postprocessing), both
for the grabbed image and for live TV.
