When browsing through the Market place, you will already be in your region. However, if you are meaning disk copies then this will not be region locked. It is the codes, games and the content on Xbox Live that are region locked, not DVD's.
I hope this helps you with your issue, Please be sure to post back here or send me a message if you have any more problems. I am normally found in the communications part of the forums or over in the Outlook and Skydive forums on Microsoft forums.
However I will reply to messages sent to me,
