When I put a +R recorded disc into my Plex 708 and use DVDINFO to check disc for errors I get error message, NO DISC IN DRIVE. There is nothing wrong with either the disc or 708 as the disc plays OK in the 708, sounds like a problem with DVDINFO. Any suggetions on how to correct this would be greatly appreciated. Thank you. Win. XP OS, using latest version of DVDINFO. The +R disc is Imation by Ricoh that I am trying to check.
