I've been looking forward to this film coming out on Region 1. Region 2 release just seems to have dolby stereo but region 1 is advertised as having a 5:1 soundtrack. (Play.com) I've also read region 1 reviews that mention the 5:1 soundtrack and praise the use of this in the underwater scene in the film. - http://www.thedigitalbits.com/reviews2/ytumamatambienunrated.html I shopped about for best region 1 price and bought from futureent.com where language is just mentioned as Spanish. Futureent are always pretty vague with their audio information so I didn't worry about this. I'm pretty hacked off to receive today from futureent a dolby stereo region 1 version. I have now re-ordered the play version with the soundtrack I wanted and will try and get futureent to take this one back. Anybody enlighten me to what's gone on or have I just been a victim of not inspecting the small print too carefully ?
