I have several DVD-R's that will not play on my DVD player, but will play on my XBox.

I performed a test previously, and it seemed that a disc would not work if ripped with DVD Decrypter, but did work when DVDXCopy was used.

Let's take one disc in particular (different than the one I just mentioned). I took this one disc to three different players, and would play in none of them - only in my XBox. So I took the DVD-R and tried to rip it with DVD Shrink, just to see if that would "fix" it.

DVD Shrink reported an Invalid Navigation Structure on the disc (immeditely upon attempting to open it). So obviously, there's my problem.

Now, the question is, how did that happen?

DVD Decrypter was useld for some, if not all, of the problem DVD-R's. I'm guessing all (should have kept better track). Is there some DVD Decrypter setting I'm missing?
