Trying to see how much of a problem I'll have with multiregion discs, seems the matsushita drives are not good and was wondering if maybe they switched to a different vendor for the new iMacs? Otherwise I'm swaying between buying an external drive which can be flashed to no-region (which defeats the purpose of the all-in-one Mac), or buying another windows system, which I really don't want to do, as I had psyched myself up to ditch Windows
