I have for some time already a DVD burner from Sony and me a long time to find such a good blank of both in my Sony DVD player (allegedly takes no blanks) than runs in my cheap players from Bellagio. I can understand the opinion of most reviews here do not confirm with me they have been recognized and described as 8x. Also have no errors detected. Poor DVD copies are not always the fault of blanks. Phillips DVD player play DVD + R, for example, preferably from. On a bad video DVD you can not measure the quality of blanks. There are programs. I have used those and get 100% error-free DVDs. And that no firmware update for my burner (including, but everything he does what he should! :-)) If it were not so, these blanks would not cut off so well in tests in professional journals. Conclusion of mine: A blank of the best quality !!!
