No, unless it's Multi-Region, it won't play Asian DVD's.
There are 7 Region Codes a DVD can have, 0 is All Regions, 1 I think is the US, 2 is UK/Europe, and I think 3 is Asia and so on.
If you have a Multi-Region DVD player, you can play any DVD from any region. (Most DVD's can be made multi-region, but I don't think the Admins will be happy if I link you to one of the sites, they are easy to find though).
