Getting DVDs to work in Ubuntu is simply a matter of checking a box in the settings, which causes Ubuntu to automatically download a decoder that allows DVDs to play. The only reason it’s not enabled by default is so that the user has to explicitly acknowledge some agreement by clicking that box.
Thanks for the post, having never used that distro I was unaware it was so easy and it does ship with the DVD working you just need to turn it on.
You have to acknowledge you are downloading and installing an unlicensed driver from another country that may be illegal. Dell won’t legally protect you, nor will this Ubuntu group.
