I have just purchased a Pioneer DVR420h Dvd Recorder. Today I made a start converting all my old VHS family videos onto DVD.I'm using DVD-RW (2x/version 1.1/Traxdata)Disks so I can tranfer the films onto my PC and edit them. However, when I try to play the discs on my PC it recognises the disc as a blank CD ?????? The discs play ok on my DVD recorder....am I doing something wrong, I've read the manual and cant see a reason for this.My Pc DVD drive is an NEC3520.
