The problem with importing from some of the Asian countries is that the DVDs come from legitimate companies with rights to distribute in those countries, but they don't always have the rights to everything on those discs like English Dubs and Subs they have ripped from say an official US release. The laws in many of those countries mean they have not done anything wrong there and they are free to distribute there, but when they export the DVDs grey areas open up and international laws come into play. So technically they may not be bootlegs, but maybe not all the rights owners have given their permission for their properties to be used or are getting paid.
As to that email what company is going to own up to doing something dodgy like selling bootlegs.
