Well, you would win that bet.  Mostly.  The media are the same at both 
places.  I bought a bunch of Sony disks a while back and have been using 
them at all my sites.  Today my contact put in a new disk he had (Sony 
too) and it is working fine.  So, for some reason the stack of disks I 
left there this past spring aren't working.  At least three of them 
anyway. 

It looks like Taiyo Yuden doesn't make DVD+RW media.  Anyone have 
suggestions on excellent +RW media?
