I'm using Sony DVD+R's and copying and burning with DVD Fab Platinum. Sometimes I go through the entire process and it says it's completed successfully but it won't play on my dvd player. It will play however on my computer. I know sometimes certain dvd's aren't compatible with some players, but the strange thing is that if I initiate another burn exactly the same way, it will play on my dvd player. I had one original that I tried 4 different times, duplicating everything the same way I did it before. ONE actually played on my dvd player. The other 3 would only play on my computer. Is there something wrong with the burner, or is it the blank dvd's? I would think if it were the dvd's, they wouldn't play on my computer either.
