This is a 4 disc set Todd McFarlane's Spawn 10th anniversary edition USA steelbook region 1 - disc 2 and 4 are fine, 1 and 3 are the problems. I followed the steps in the sticky - using latest download/set anydvd to default and attempted to rip dvd to hard drive. Disc 1 seems to view several of the VOBs as empty at the end of disc 1. It reads through the first title set, then says "Repairing defective DVD structure", then hits title set 2 and finishes very quickly. Disc 3 fails reading after more than half the disc. Both discs play fine in a Samsung blu-ray player. Disc 1 produces no error after finishing the rip but resulting folder size is 1.68gb. The disc size is 7.63gb and it doesn't play any main titles. Disc 3 error is FileIO 3 VTS_02_1.VOB 1266784256 43008 and fails reading, I'm guessing at the layer split. Disc plays fine in the standalone player. The physical media is free from scratches and damage. Thanks for the help!
