richUK,
Reply to your second post and link.
Not all sure what you are linking to, but the entry from TonyPh12345 makes perfect sense to me. I see great improvements in posterization/bands when outputting 12 bit from WD TV to my TV. And as written by TonyPh12345 the higher bit depth has an advange in the decompression of the video data. I see the improvement both in the shaded blue background of the WD TV screens, and in movies (simple scenes with shades).
Thanks once more for your input.
