I have copied tons of DVD's and just now having a little problem. My friend wanted me to copy some of mine for him, which are all pretty much copied. The copy's I just got done doing for myself copied for him perfectly, but the older ones I have won't rip, copy, or shrink. They play perfectly in any player, yet I can't copy the copies. The only difference that might help you is that some of my old media is DVD+R and all I use now is DVD-R. Also, I have a new burner and the ones burned on it are the ones that still will copy. But the others play fine.
