I have had some media / DVD stand alone players non compatibility also. From my own experience, even updating the firmware of my LG 4160B, some times I record a DVD for a friend and he can't play it on his Pioneer DVD (a 2000 model, which plays all regions!). I noticed, from your comments above, that you recommend to "set the booktype of DVD+R to DVD-ROM" and use a slower burning speed. Question: 1) How can I set the booktype of DVD-R to DVD-ROM using Clone DVD 126.96.36.199? I have heard that this increases the compatibility between media brand & DVD player. Thanks in advance for your kind cooperation.
