Did anyone else's DVD...

jump back to the start of the movie? well, almost the start. SPOILER: after the guys reverse time and the screen blacks out, the film started playing again from their conversation in the pub. we assumed it was a flashback, but it was going on for ages, and eventually we checked scene selection and saw our DVD had jumped back to that scene. It seems like a crazy coincidence, and as Cassey said, spilling the beer had caused an infinite loop....Was the jump a gimmick made into the DVD? Or a freakish coincidence? I can't find people talking about it, but it seems too unlikely to happen by chance. If it was on purpose, i can see why they did it, but it was damn annoying!
