I noticed that my mac mini won't read dvd-r's and upon inspection...with all macs under the detailed specs in the small print it says: 8x double-layer SuperDrive (DVD+R DL/DVD±RW/CD-RW) ...no where does it mention dvd-r, just dvd+r so does that mean that the superdrive won't burn dvd-r's at all, just dvd+r's? If so what an oversight on Apple's part that is IMO...
