I ripped a region 2 dvd and I used smartripper to do it. I ripped an episode and it was supposed to be 40+ mins. long but it says 35 mins. and I ripped it with no errors. When I compare it to the original dvd they both play fine, but the ripped ep. time stops at 35 mins. yet the movie keeps playing the full 40+ mins. for some reason. Why is that?
