I tried installing AcidRip as well, and get the same results.
Is libdvdcss installed? Most GNU/Linux distributions don't ship the library needed to decrypt and play commercial DVDs, as it can be illegal in certain areas. If you don't remember installing this, open up the terminal and type:
sudo apt-get install libdvdread4
If this doesn't work or you've already installed it, it's probably a problem with your home user not being able to mount/unmount it correctly under HAL. (That is, if Ubuntu still uses HAL.. I haven't used it for a long time.
