Hello, i've got a problem with my region code settings for playing dvds. It should be in Region code 4 (australia) but i changed it over to region code 1 to view an american dvd. Now when i put a region 4 code disc in it says "The Dvd-Video disc region code does not match the drive region code. You can not change the region code for your drive." I am aware that there is a limit to the number of times you can change the region code but i had a few more changes left. This is, as you all would know, extremely frustrating! I have a Mac OS X 10.4.6. Any help would be much appreciated. Thanks.
