If you are new to making DVD copies you need to find a disc that suits your machine and stick with it. There are cheaper discs than Traxdata but you may well end up with a bin full of "coasters" and high blood pressure. It's so annoying when you lend people an unreliable disc.This disc was voted Best Disc 2004 by the readers of a Hi Fi Mag so its not just me.I use them on 3 different machines including lap top and no problems.I bought an amount of Hyundai DVD blanks and they all get rejected on initialising. Buy sleeves to keep Traxdata from scratching.
