I've been copying on Clone DVD and have found they some of the movies are actually copied and some say "no disc" in my DVD player. I'm using a brand new burner from CompUSA Internal Double layer DVD=/-RW Drive w/ Lightscribe and burning onto DVD-R 4.7gb 16x recordable media. I've installed all my updates for CloneDVD. The discs will playback in one DVD player but not in another in my household. Now I'm taking a trip and all I have copied will not play on my portable DVD player except one I have copied. Also what is the usual record/write time? It takes sometime up ti 1 1/2 hrs for the whole process. Any help would be greatly appreciated!!
