Are you just trying to play back the iso? Have you tried playing back the ripped folder? Did you make the iso from AnyDVD or CloneDVD? If AnyDVD, do you remember the pop-up warning that came up telling you that it isn't advisable?
A quote from one of your earlier posts:
That's not how it's done. Make the iso using CloneDVD from the ORIGINAL disc with AnyDVD running, not an AnyDVD iso. The warning about making an iso in AnyDVD (from a DVD) is there for a reason.
Yes I was just trying anything different at this point as the normal way of doing it was not working... but only on this disc. Again I believe I am dealing with a bad pair of discs.
