My girlfriends Powerbook is from Japan, so is region 2. I tried putting in an iDVD made DVD from my US (region 1) Powerbook and it came up with a screen saying it wasn't compatible (I thought iDVD made region free DVDs... I chose NOT to change her Powerbooks region. After taking the DVD out and putting it back in a few more times (always choosing NOT to change the region), I decided to try running it in VLC. It worked in VLC. I decided to try other region 1 DVDs, and they all worked. I thought that was a bit fishy, and I found that her powerbook is now region 1. Did VLC automatically change the settings of the Powerbook? Does Apple have it set to automatically change after a few attempts? Anyone have any ideas? Thanks in advance.
