Hindi movies have different distributors across the globe.Lots of dvds are for sale in India only but people would buy and bring to the US.
But there are at least one on line store that sells these dvds in the US.
Are those dvds considered pirate

Nopes. The DVD itself is not a pirated DVD, though the person may be acting pirate-like
Selling an otherwise genuinely produced DVD, in a location, from within that location, where it cannot be sold, may be illegal, but the disc remains non-pirated.

The same is true for English movies... the same English movie may be distributed by, say, Excel Home Videos in India, which is being done by Fox in UK, and maybe Focus in US...

Is that why Shemaroo sells only a few dvds on their international site.They only sell the bulk of their dvds in India only. Maybe I need to find someone in India and buy the dvds from Shemaroo then they will ship to the India address. Then get it shipped here in the US. Unfortunately I know no one in India,

You can post a request here on zulm also -- maybe someone can respond.
