The problem could possibly be with the rip software, but my Windows browser may “reject” what it sees before the application can see it. NTI CD & DVD Maker recognizes these discs and knows how much data is on them. But Any Video Converter Pro, Intervideo WinRip, Intervideo WinDVD, Avex DVD & Video Converter Pack, and AVS Video Remaker all respond with the same MS Windows error message (L:/ is not accessible. Incorrect function.) my browser gets when I try to access the burner’s drive letter with them. This is the same message I get when I put a blank disc in the drive and attempt to access it.
It is a good bet that using -RW media is at the bottom of this somehow, since I have sampled about a dozen discs written on my SONY recorder and only the “-RW” discs present a problem. However, it is not JUST that. Both my burner drives are supposed to work with -RW media, and indeed I just experimented with my current batch of blank media, creating a data DVD on my PC and then attempting to access it, with everything working as it should.
I have just launched another experiment aimed at recovering what I have previously recorded. Since NTI CD & DVD Maker has no problem with the discs, I am using it to create a copy - on DVD+R media. I will see how that works and report when it is done. However, if it works I will be even more confused!
Thanks also for the link to info on the VR format.
