I have a 12" powerbook 1.33 Ghz and when I bought it was able to burn dvd-r. (if I'm wrong on the original spec I apologize and this is a moot point). But today I was looking at the system profiler and the disk burning section showed I can burn dvd +r and dvd +rw. I read somewhere the drive was capable of such a feet but was disabled for some reason. Is this a feature of Tiger enabling dvd +r? If you know anything I love to know! I've added a screen shot from my system profiler. Thanks!
