I've experienced same audio/video stuttering , when I was first time playing with game settings > solution would be to set up audio> soundtrack/music from "shuffle" to "sequential".After doing it once I've never experienced this problem again. I've made a post about this week or two ago . Also, it helps a lot , if game is installed to HDD, because there is a lot of streaming involved and could get very tiresome for DVD player . (XBOX360)
