i bought dragon ball z budokai hd collection from U.S.A and my xbox 360 from india,it shows doesn't support region code

you need either a region code 1 player or a region free player.

there is no other way.

you can change the region code on your xbox360 however if you currently live in india you may not be able to buy games locally and play them which would not be good.

it would be better to just use a cheap dvd player and change it to region 1. something in the $20-30 range that you can just use for region 1 imports

or, if you now live in the usa perhaps you want to swap all of your equipment over to region 1 and use a cheap player for any older movies you have which are not region 1.
