Have checked the price in PLAY for this title with R1 and R2. R1 costs GBP 17.99 and R2 costs GBP 9.99, this is a big different in price when both are having dts, so are there any real different in terms of sounds and picture quality? What is the main different between them then? I noticed on the description that r1 has 25 min deleted scenes while r2 has 20min only, and r1 has "7 Minute Montage of Additional Unused Footage" but this is not mentioned in r2. Thanks.
