The TDK "Armor plated" DVDRs that I'd purchased over a year ago are still working fine.
I switched to Verbatim with VideoGuard technology about six months ago. I tried the steel wool test on one of the Verbatim discs, and it does still play.
And being TDK is not manufacturing their own DVDRs any longer, it's a crapshoot as to who is supplying the discs for them.
The extra protective layer on these type of discs does resist rough handling better than standard discs, but it's really the dye that counts when it comes to longevity. Verbatim prides itself on using high quality AZO dye that supposedly will stand the test of time. So far I have Verbatim discs that are four years old, and they are still playing without a problem. This of course is not the case with many other brands I've tried.
Verbatim will soon be releasing a special archival quality DVDR. You can read about it here:
