Interesting. I had to go through 8 other reviews before I found anyone else complaining about compression artifacts in Hunchback. Most gave the video a 4/5 or B rating.
Seeing those screenshots, I cannot disagree though. It is artifact-y.
I'll probably be watching Hunchback again this summer on a really large TV. Should be interesting to see what is visible.
I see the guy at videophile also said he prefers the R1 disc just because R2 PAL speedup is a bigger deal. I can't say I disagree.
I updated to mention the grain in the guide, but I'm not sure it effect the 'best version'. BD > R1 DVD unless someone decides they want to release a custom disc.
