Movie Only Rips Not Working

I’ve attempted to Rip Blu Ray Movie only to ISO and it’s not working. I’ve first Ripped the full movie to ISO using AnyDVD HD. When I play that ISO it works fine. But when I take that ISO and Rip the Movie only, the movie is unwatchable. After about 10 minutes the video starts freezing but the audio keeps going. I’ve trying version 6.0.1
Thanks
