Ok so i have been ripping for a few years now with always awesome results.I use prodisc although recently i have ran out.I had a stack of blank dvd-r media lying in a cuboard though they are unmarked without any branding i can't remember what make they are.I used to use a peice of software that could tell me what media i was using.Does anyone know what this software tool was?Any help would be much appreciated thanks.
