Is rush hour 3 the only one you've had issues with? I ask a lot of questions here, so I try to help where I can. I don't have Rush Hour 3 yet. I actually looked at it this weekend, had it in my hand, then put it down and bought 310 to Yuma (good movie), and a few others instead.
Maybe I'll pop down to the store and pick it up and give it a shot. Looks like you are doing the same command I was, I really hope there isn't yet another copy protection out that screws up ripping. Hopefully it's not a version issue either, I wiped out my old mythtv setup to install lmce, and just now installed vlc.
