Well I haven’t found anything about this on the Forum or in the News so Im going to write it down here.
OK what I wanted to tell you is that I found an Firmware for the Pioneer A05 / 105 that allows you to write most common 1x DVD-R brands on 2x Speed.
I allready tested cheap Princo DVD-R 1x at 2x Speed and I can tell you that it works with RECORD MAX 4.5 & Nero (Second Newest Version)
On www.dretschler.com (german Page) you can find 100er Cakeboxes of Princo 1x for around 130 Euro.
PS : Sorry if this is an old hat and all of you allready know about this. Also I’m not responsible for Bad Flashes & Malfunctioning Drives.
