In the thread "PLEASE HELP- region codes" in "Discussions > iDVD > iDVD4 and earlier", using Panther I reported " I inserted a different region code disc, got the message that I only have 3 changes left, then the error -70001. "
After upgrading to Tiger last August I reported " just upgraded to Tiger 10.4.0 and the problem was still there.
Then I installed the software updates to 10.4.2 and DVDPlayer 4.6: I am now allowed to change the region code."

Howwever, last month I had the problem again, possibly after installing 10.4.3: "3 changes left" and "error code -70001" on inserting a disc with a different region code.
The solution I found was to use VLC, a DVD player which ignores the region code, rather than the mac os X DVDPlayer.
