I downloaded a DVD from a.b.sw and I am trying to extract the material in the rar's. I started at night with WinRar, and I looked and had 400 errors. I then looked at the Video_TS folder which should have been around 2.5GB, and it is only 75MB. My point is the set comes with Par2 files. What should I do with these? Will they help my 400 errors go away?
