well, i use clonedvd 1.2.8.4 and i have succeeded in copying some dvd's but sometimes i burn a dvd that i can also only read in my dvd-writer and not on a regular dvd player. I think that is because clone dvd use the highest burningspeed to burn your dvd's and that is exactly the thing i don't want it to do. I have also udated my firmware and all but nothing seems to work, 1 time i have a good copy and the othertime i can throw the dvd away because only the writer can read it and no other dvd player can.
So my guess is that the problems u guys have, has also something to do with the speed that the dvd is burned, but i dont know how to fix it
