The only problem is that it's really hard to put a true cost on the impact of piracy.
As a percentage of the DVD buying public, how many actually have access to the far-East copies? How many of those are actually sold?
I don't doubt there are lots of them sold but I'm sure the movie studios do their best to inflate the numbers to their benefit.
I'm still holding firm to my no HD DVD / BluRay purchase until next year.
