As far as content goes, the R1 version of this disc would appear to be identical barring the NTSC colour format used in the US. There are, however, a couple of minor differences. The R1 release is THX Certified. It also has a French 2.0 Dolby Surround audio track. However, it lacks the Spanish and Russian 5.1 Dolby Digital tracks and our slew of subtitle options. Given that there is no substantive differences, I would suggest working out your language requirements and the price difference and go with that. I would be curious to know if the R1 release has a better timed dual layer pause as that might still make it the winner. For the moment, I am going to mark these as the same.
