I've loaded everything suggested and almost all the multimedia apps available, and my DVD's will not play. The device is found, /dev/sr0 as well as the required links to /dev/dvd (for some programs). Every lib…so has been found and installed. The codecs are current. Somethings missing still.
I removed and reloaded the addon's to MPlayer, Totem and several others. I added the Ubuntu Restricted (MP…, AVI etc) additions. I've removed and reloaded Totem, MPlayer, VLC and several others and reloaded the addon's and plugins again.
I verified that the links to the Devices are correct. I removed and reloaded the available codec's. Note: Those Videos I created on DVD from my BeOS System Play just fine. Further the digital copies play fine. It is only Original DVD's that are giving me fits. Windows Vista play them on an alternate boot drive.

I had a similar problem with a DVD drive. Once I booted into Windows and played the DVDs, everything worked fine in Ubuntu. It was suggested that Windows set my drive's region, which is required to play DVDs.
I don't know if this is the case for you, but it's easy to set your region.
Insert the DVD into the drive without playing it or accessing it.
