I was able to burn with nero 7 and it works in my dvd player. However, I had to get a new burner and nero 8 came with it. All the DVDs I burn with nero 8 on that new dvd player don't work (although they play on the computer) DVD Shrink even comes back and says burn was successful.
DVD Shrink doesn't burn and cannot be linked to Nero 8 for burning. If you are autoburning you should revert back to Nero 7 or use Imgburn for your burning.
