Hey guys I dont know who to ask about this so I figured you guys would probably know. I built a duplicator with an Athena 1-11 Sata Duplicator controller 10 Samsung Light scribe CD/DVD burners. All i'm trying to do is make promo discs for my band. I've tried a number of different Medias. It seems that anything burned on my computer works on everything regardless of media but discs burned on the duplicator only work in certain cd players on the SAME media. Like ill burn a master with my computer and the master will be recognized in my computer as soon as its done. however if I take that master and duplicate it on the SAME MEDIA with the duplicator any of the copies wont be recognized in my computer. But will work in some car stereos and some computers but a lot of people think they got blank discs. It doesn't seem to be any specific thing either. I began testing cds I burned on a cd walkman from like 1990 and they played fine but the discs wont play in some car stereos in brand new cars. Rather then switch to media that is super expensive and pretty much kill my ability to make 300-500 free cds for each show cheaply I have decided to try replacing the duplicator controller. Anyone have any recommendations?
