Are there any other differences between broadcast and DVD other then the openings?
Music for sure, and I think the first episode of Season 6 is cut on some foreign releases but I never actually got confirmation on that. I’m pretty sure the syndicated versions of S6E1-2 are cut.
The international DVD releases of the season 6 premiere are cut to remove two shots to the deer sacrifice scene, the US DVD is uncut in that regard
The two part version of the season 6 premiere is what’s on streaming and my estimate is it has about 3-4 minutes cut compared to the original “movie” version on the US DVD
