I have been using MacTheRipper and everything tends to go well - with a few exceptions. Lately I have been getting error messages when the movie is 3/4 of the way finished ripping. The errors say "Mirror of DVD Failed", "Mirror of Title Set 1 Failed" and "Read Failed for 512 Blocks at 2356299". Sometimes after I re-clean the disc and restart my computer everything works fine. More often then not I cannot find anything to fix these errors. I cannot figure out if it is the specific disc or my computer, or program. I thought that maybe when the disc was older and more damaged maybe that would be a problem. I just tried it on one of my brand-new movies and it did the same thing. It seems to effect about 1 of every 3 movies. If anyone has any advice - or solution I would REALLY appreciate it! Thanks so much!
