Don't fool yourself. These were not legal copies "made" in China. Those box sets you see floating around Ebay etc are pirated copies.
1. Pirated DVDs are usually being sold at amazing prices, too good to be true sums it up
2. Pirated DVDs may have asian characters on the cover and/or discs.
3. Pirated DVDs are being advertised as all region and the official Asian release
4. Pirated DVDs are those which are not available for purchase from retailers,
ie, seasons of TV series not yet released.
5. Another thing to watch for is the country of origin. For instance I only sell
US releases which ship direct from our USA warehouse, this guarantees legitimacy.
US releases are not available for sale from Australian retail stores (legally anyway),
if a title is advertised as Region 1 and is located outside of the USA it may not be the real thing.
