Problems with CDR-audio blanks?

I own two Marantz DR-700 CDR audio recorders. I've started to have a problem with both machines ( which makes me doubt it's the machines) - the initial stage of recording a one time use CD audio blank involves the machines scanning the disc's looking for errors and to make sure the disc's are registered as "audio" recordable CD's - this process is called OPC - what's happening is that entire batches of CDR-audio blankks are failing the OPC - they can't be recorded on.
I have used hundrerds of Memorex blanks - these quit working in my machines , just tried 5 Imations - no luck - went thru two 50 pack spindles of Maxell's - no luck , TDK's work fine ???? To clarify - once recorded - even older recorded disc's PLAY fine - it's recent purchases that don't seem to be recordable.
Anyone else expereinced this problem? The answer is ???

Appreciate the help with this problem. Have tried a couple of things - one which seems to work flawlessly - "Fujifilm CD-R All Purpose" blanks work flawlessly. Available from Office Max.
Talked to a tech at Marantz today - he said that DR-700 were designed for 74 min. blanks and will probably have problems with 80 min. blanks. Frankly both the Fuji's and TDK's that I have tried and which work are 80 min. blanks - so I'm not sure he's right about this. I am going to see if I can find any old stock 74 min. CDR-audio blanks floating around to test his idea.
