Thanks for your review!
About abnormalities:
1) you are completely right, I'm afraid! This was due to the very aggressive noise reduction I used to delete all those scratches and drop outs (often HUGE) present in the sources - that in this shot was confused - and sadly I didn't notice it when I watched the final version... maybe due to the fact that there are only few frames inside a flashy shot, or maybe I blinked the eyes too much there, or... don't know, but there is definitely an error, and it must be corrected!
2) this is in both HDTV sources (even in the retail DVD!) - probably it's a "patch" in the master to replace a corrupted part:
