Review on Sony 25DMR47SP DVD R 4 7GB Recordable by Doug Taylor

I have been buying recordable DVDs of this type and brand for many years. Typically a small percentage of the disks in a package will not work, maybe 1 in 20. Usually the registrar will reject them, immediately "self-checking". On rare occasions the disc works fine until I try to finalize it. However, every disc from 3 of these 4 packages was not accepted by my recorder. (I've tried a few from each pack except the 4th one which I never opened.) I'm only rating them a 2 not a 1 because the seller was very willing to refund my money and the cost of returning it take over.
