The following is perhaps an FAQ for more experienced members but I could not find a ref on other posts, so here goes: I understand the external superdrive for the macbook air is stuck on a "region" for DVD viewing (US vs. Europe, etc). This can only be changed a few times before the drive locks into the last regional position chosen. I travel constantly from one continent to the other and have batches of DVDs from both sides. My question: is there a workaround to allow the drive to switch endlessly from one region to another (I recall there was one for older iBooks)? Thanks for any help.
