Problem with Nero 6

I’ve used Recode 2 and Burning ROM for years, and a couple days ago was the first time I’ve heard this problem.

After the burn is complete, I play the backup copy using Nero Show Time, and this is the first time I’ve heard the audio portion slow down and the audio quality sound chopped up. It really freaked me out!

Now when I take a DVD from Netflix, and try to play it in Show Time, I hear the same garbage. The video also looks like its struggling to show.

What is the fix here. Thank you all for any help.
