Are new DVDs being made differently these days? I bought a stack of MEMOREX DVD+R discs 5 years ago and have been using them to record on my Sony DVD/VHS machine, bought in 2007. I just got a new stack of identical discs, DVD+R 16X 4.7GB, and they will not record, After 'formatting' the disc there is a pause then I get the message "this disc can neither be played or recorded', But when I insert one of my older blank discs, it works OK. I have tried memorex and Sony discs but neither will work. What is wrong and how do I fix it?

Even Memorex (a "vendor" for this discussion) outsources some/most/all of its DVD blanks to other manufacturers, and those companies can change, and even a given company's chemistry and quality can certainly vary by design or even by country of origin.

This is still being discussed at multiple websites. I recall that at one time club.myce.com had very active discussions of from which manufacturer a given vendor sourced their media. There are also free/donateware programs out there that can tell you which manufacturer actually made a given disc...and some of the "quality name-brand" vendors get their discs from absolutely crappy manufacturers.

Example of one such discussion...

I'm pretty rusty on all this as I don't use optical media much anymore. HDDs are vastly $/GB cheaper now than optical media for system backups. But here's what I can offer.

At one time, discs manufactured by Taiyo Yuden were considered the consistently best, and multiple vendors repackaged and sold Taiyo Yuden discs...but even those vendors bought from other manufacturers and it could be a matter of luck as to which manufacturer actually made your disc(s).

And of course you have to make sure the disc format is compatible with your drive. A given standard can have changed between the older drives and the newer media. Even disc packs you've been buying for years can change compatibility without warning. Plus, some manufacturers' discs are "more compatible" with some drives and even drive firmware than others...and that changes year-to-year. I think there's a club.myce thread on that. Some people even use software settings to force their drives to run slower than a given disc's rated recording speed (vibration at higher speeds may reduce alignment accuracy and result in poor or unusable recordings on a given disc/drive combination). For example, I generally limit my recording speed to 2X even if a disc and the drive both claim 16X recording capability. You might try something like that to see if it makes a difference. There are also programs out there that force-limit a drive to a user-defined maximum speed even if the burn software doesn't actually contain an option to change it.
