Thank you so much.  It was only just that one clip that looked great in Retinex, the rest didn't give good results, too much Blocks.  Also to add to the list C: if there is hardcoded subtitles, it flickers too much and is unusable.
Looking forward to reading your updated guide, I've been always fascinated how you overcome these obstacles.
