I have a Mac G4 and a PeeCee and I went to NewEgg and bought two identical DVR-109 drives and both have worked flawless in both machines. In the Mac I use Toast for mostly data and music CD's and DVD's and I do all my movie DVD's on the PeeCee due to the availability of software. I have done several hundred with very little problems. I have also burnt at 4x and 12x. Never had a issue with either speed. I also have both drives flashed with 1.58 and modded with the A09 and Quietdrive.
