After searching thru the threads, I haven't been able to find a reasonable way to identify the DVD media manufacturer. I've tried Nero InfoTool and a few other programs, including DVD-X-COPY. Others here post that they read the manufacturers id apparently with ease. What am I missing? My 105 drive will burn 4x ok, but I would like to know if the bulk packed, supposed Ritek media I have bought is the real thing.
