I just received the replacement disc, and the repeating clip has been fixed. I can't say anything about the lip sync issues, because I never saw any (and I'm pretty picky about that stuff).
I purchased "Starship Troopers" over the weekend, and the disc has the repeating frame. Called customer service and got my reference number. Will be sending the disc today. Customer service said if everything goes smoothly, should have the correct one in 2 weeks. Hope they are right.
