I have used these Verbatim brand 16X disks in both my DMREH50S Panasonic DVD Recorder (recording content from the television to its hard drive and then after editing the content, burning it to DVD media) as well as my pc computers NEC ND3500AG 16X DVD burner and all I can say is how pleased I have been. These burn very very fast at 16X and I have not had any failures using them absolutely no errors so far! I have used other popular brands of 16X speed DVD media including Taiyo Yuden, Philips, Maxell, Memorex, TDK and while those also have burned very dependably (with a few exceptions) there is one capability I have noticed that the Verbatim brand possesses that those other brands do not. And that is I can squeeze more video and file content onto these Verbatim disks whereas with those other brands I cannot! There is a little more storage space on these! That has made a difference at critical moments in which I needed to fit those extra few megabytes onto the same disk. I am on my third 25 disk spindle and undoubtedly will opt for the 100 disk spindle when the time comes to replenish my supply. I have decided that I wont use any of those other brands until either the manufacturing quality of these changes for the worse or they stop making them altogether I hope neither happens. Anyway, these are as near to perfection for burning video and files onto as I have been able to find and I recommend them to you heartily! http://garyadair.com/324538
