16-235 -> 0-255; [SD] Applying expansion only to BT.601 [SD] material is wrong, as BT.709 [HD] is limited to "16-235" as well, the only full range YUV colorspaces are: JPEG (most variants), Digital Cinema (JPEG2000 variant), FRAPS video and many studio formats.
This shader is intended for situations were the decoder/renderer/driver doesn't do the correct expansion. They are not for general use with a properly functioning playback chain. For example, some ATI drivers mess up, but only at SD resolutions. Hence, the "[SD]" part, which simply means the shader only operates on videos with SD resolution.
