I hope this is the right forum for this thread. I've been looking at the Pioneer DVR 109 (OEM/bulk) dual layer "superdrive" as an upgrade to my existing combo drive on my Power Mac G5 (runs Mac OS X Tiger). Just today, I saw the Pioneer DVR-A09XLB for around the same price on www.buy.com (after rebates and discounts). I remember reading that these models are identical and that the DVR109 is an OEM/bulk model whereas the A09XLB is the retail model. I also checked some sites and it looks like the retail model, apart from the bundled Windows software, also has some kind of dust filter and is supposedly quieter. Since I've followed the price of DVR109 for some time and have been reading about it in various sites (including http://www.xlr8yourmac.com), I feel more comfortable with it. But what I'm more concerned is about the firmware and how well it would perform on the Power Mac with Tiger (at the highest read and burn speeds). Does anyone have any experiences/thought/suggestions to share about which one might be a better choice and easier to install and get working on a Power Mac G5 running Tiger? I'd also like to know if I've missed out anything in my research.
