From Wikipedia: http://en.wikipedia.org/wiki/Rovi_Corporation#RipGuard : RipGuard In February 2005, Macrovision introduced its RipGuard technology designed to prevent or reduce digital DVD copying by altering the format of the DVD content to disrupt the ripping software. Although the technology can be circumvented by several current DVD rippers such as AnyDVD or DVDFab, Macrovision claimed that 95% of casual users lack the knowledge and/or determination to be able to copy a DVD with RipGuard. technology. (I doubt they're going to tell you exactly what it does in that article. :) ) And welcome to our forums. :)

Thanks :) I was kinda looking for something a little more specific though. I thought it added some dummy/empty cells at the start of a protected VTS or something to disrupt the ripping tools. But I'm not very clear on it.
