This may be already known, but it was a surprise to me when I created a slideshow with iPhoto and iDVD. Although the Pioneer 111D DVD writer is shown in System Profiler as being unsupported, I was offered a choice of the internal UJ-846 or the Pioneer to burn my project to. I next tried burning a folder, and it also burnt fine, as did iTunes.
This is on an iMac G5 with Tiger 10.4.7 and the drive in a FireWire case. It makes me very happy, after many fights with the UJ-846 to try and get it to burn a DVD reliably -- I have enough coasters for a very large party :-). I have seen reports of the Pioneer 110D working fine, but none for the 111D. Anyone else care to report their experiences if they have one of these drives?
