My R1 came in 2 days from CD-WOW! Box was in perfect shape and only cost £49.74 - using the 192 option.
Not heard the DTS track yet, but looked at the bit rates. The DD track runs at 384Kbps and the DTS track runs at the usual 754Kbps. So there should be some difference (don't know why The Digital Bits never noticed any difference).
The interactive field guide is pretty neat, though. It gives you lots of info about the men of Easy Company, maps, time-lines & so-on.
