I took my time registering because we (me and a friend) started suffering from these errors since yesterday.
We are using Verbatim DVD+R DL MKM-001-00 (India) and about 1/2 of the burns gives the same error. The first error was while closing session then now is just the same as the thread starter: Invalid Address For Write....no matter if burnt @ 2.4x or 8x
My system is Windows Vista Home Premium 32 bit with a Pioneer DVR-116d.
One thing to note is that all begun after installing some recent windows updates...but I doubt it has something to do...
