I use a standalone JVC DVD recorder to record to a DVD-RW, finalize it and then use DVD Decryptor with the LG GSA-4120B drive to rip it to my PC for further processing. Recently I made a recording that would not read on my LG drive. All programs including DVDInfoPro recognize it as a blank disc. Yet I can read the disc just fine with standalone DVD players and with a generic DVD-ROM drive on another PC. I am using firmware A111. Since my JVC recorder is now broken I can not make any new discs to test. I am using Memorex 2x DVD-RW media and have never had any trouble before. Any ideas as to what could be the problem? Thanks.
