Is it possibile that 0-255 and 16-255 selection is incorrect and inverted?
When a video is played in hw accelerated mode, for example, a calibration video to clipping and set blacks and whites bars (typycally in NV12 4:2:0 space color, limited 16-235 range) and the 'Dynamic range 16-255' is selected, Avivo HD/UVD seems convert the range from 16-255 to 0-255. That's odd because the operation, that work fine, should work when the 'Dynamic range 0-255' check is selected not the other one. The same features is avaiable also in Nvidia panel control but in that case the selection seems coherent.
