Having a region free DVD opens many doors in DVD viewing. I've been seriously getting into HK DVD's lately and I noticed over at www.bulletsnbabesdvds.com that most of their recommend DVD's are R2. Is there a reason that the R2 versions are that much better? I'm psyched to buy Iron Monkey because when my wife and I went to the movies this weekend, we saw a preview for it and it looks great. I get home and notice that this is already on DVD. I could buy the one here or order the R2 version from Amazon.uk but I just want to know the reason. Thanks.
