Nothing plays DVDs in Ubuntu Gutsy?

[Lee Tambiah]

Hello,

To test this I inserted a commercial DVD, where totem then opens to
attempt to play the disc but returns the error "An error occurred -
Could not read from resource".

There are some packages that CANNOT be included in the Ubuntu
distribution due to  legal reasons such as copyright, license's and
patents. However you can add them using the Medibuntu Community
repository. I do not advise using the etch repositorys as those
packages have been tested on Etch itself not Ubuntu, its not a good
idea to mix packages from other distributions.

Adding the libdvdcss2 library also made the DVD play with success, for myself.
