Problem with Video after compression

[WuPhilly]

I started ripping movies to my hard drive using DVD Decrypter and I'm using AutoGK to compress them, however, the last 2 movies I've done have come out all blotchy with the video... Like there are constant distortions with it that pop up such as boxes and bars if that makes sense. I've tried redoing them a bunch of times, even uninstalled AutoGK and re installed it, and I've done it at different quality settings but the same thing happens. Any Idea as to what's wrong?

Amendment.... I just played the full video before it was compressed, the version straigth after DVD Decrypter and it had the same problem, so I guess the problem was from that.. Any Idea's how to fix that?

Sounds like a bad DVD or your burner is having read issues when RIPping the disc. Aside from that, ensure you have the latest version of DVDFabDecrypter.

Let me guess... Your original video is from Sony Entertainment. Correct?

Can anyone say "Ripguard" (or whatever Sony calls it)?
