"People’s store-bought DVD collections are always copy-protected or DRM-ed. In 2006, the U.S. Congress passed the Digital Millennium Copyright Act (DMCA), which made it illegal to circumvent DRM (Digital Rights Management) protection on DVDs. This means that it’s illegal to create a software program that can bypass DVD DRM protection. Another way of saying it is, the moment you crack DRM to rip the DVD, you’ve violated the DMCA.
However, the DMCA contains an exception for “fair use.” This means that you can legally rip a DVD for personal use, as long as you don’t violate any of the other copyright laws. What does this mean in practice? You can rip a DVD for your own personal use, but you can’t distribute the ripped file to others. You also can’t make a copy of the ripped file for someone else.
So, in a nutshell, if you rip DVD’s and restrict the copies to your own personal use, you’re probably safe."
The only reasons they would be aware of this to sue you would be if you or someone else told them. The likelihood of that is pretty much nil unless you do something that is illegal (like selling ripped media), in which case they’re more likely to just come after you for that.

“Probably” being the operative word there. The MPAA could still sue you into third world poverty to prove a point even if you end up winning the case.
