R1 DVD9 rip It was another useful experience for me, maybe I will continue do the other Volumes, but in my opinion, the R1 not worth as they use some Dot Crawl Removal method that did strong vertical blur with lut mask to protect black lines, and they did it in fields, it did good job in Dot Crawl Removal but there are a lot of side artefacts, like killing some White pixels and did some black ringing that happen in the top and bottom of black edge, I hope I get the R2J DVD
