Here is for PAL, and video levels to PC levels expansion:

Input_Bit_Depth          8
Input_Video_Format       PAL_DVD   YCbCr
Output_Bit_Depth         16
Output_Video_Format      PAL_DVD      RGB_PC

For NTSC use "NTSC_DVD" and if you don't want video levels to PC levels expansion use RGB_Video.
Soon I will open a thread for cr3dlut helping and discussion...
