I just got the new Macbook Pro 15'' unibody aluminium with 2.53ghz and 4gig RAM with last OS and features. I tried a film DVD in and surprise, no programs is preinstalled to read DVDs. I was able to get Mac DVD player from MAC OS X Install DVD using Pacifist. It ask me to give the Region Code which is Region 1 (so are all the DVDs I tried in the drive). I click "set the drive region" and here comes the message : There Was A Problem Changing The Drive Region Code ERROR: -70001 So, I tried VLC media player. Opening disk just don't do nothing. Opening VIDEO_TS file is the same. I looked on many forums and find the idea of repairing disk permissions in Disk Utility. It didn't work... It's brand new and Im so pissed. It is only a software problem I guess... Would it be necessary to erase disk and reinstall Mac OS X? Thanks for you help.
