I want to order a few R1 DVD's but this note from http://www.play.com has put me off some what.

Regional Coding Enhancement (RCE): has been added by Warner and Columbia to certain Region 1 DVD’s. RCE will prevent the DVD from playing on some “Multi-Region” DVD players. If you are in any doubt that your player may not be able to play RCE DVD’s, we recommend that you do not order this title, as we are unable to accept returned RCE DVD’s.

Does anybody know if my DVD Player with the Region hack, play these RCE disks?
