My R2 Straight Story is DD5.1, bought from play some time ago. One of my favorite films, at least until I tried it in my brothers Play station2, side ways up and it scratched the bloody hell out of it. Either going to buy again or try a DVD fixing kit. Probably cheaper to buy again
Region 2 Shawshank is definately only Dolby Surround. It may say DD on the packaging, but I think VCI were confused and meant DD Surround, rather than DD 5.1. It was an early VCI release, and they have recently re-packaged it, but it's still the same transfer. Picture quality is awful by the way. I ended up ditching my R2 version and going for the much improved R1.
